When it comes to blast mitigation, it is important to consider a number of factors. First, the distance between the explosion and the surrounding area must be minimized. The impact of a single bombing can damage buildings several blocks away, but they can also be damaged if the surrounding area is not adequately protected. In the case of Nashville, where the bomb was detonated by a truck, there was no standoff distance and buildings close to the explosion had significant damage.
Buildings are often designed with static loads in mind. When considering blast mitigation, engineers must account for the dynamic response of the structure. The structure must be able to withstand the impact of the explosion without collapse, as well as limiting damage to just one part. For example, a building might need thicker columns and wider walls. In addition, a security guard may need to be deployed for protection in a specific area.
For building owners and managers, a blast mitigation system is an important consideration when planning a new building. These systems can be applied to walls, columns, beams, and roof panels. When installing blast mitigation systems, remember that the threat level must be converted into equivalent TNT quantity. If there is more than one threat level, the resulting pressure and energy levels must be calculated. If an explosion is expected, a building or structure must be constructed to withstand both the blast pressure and the resulting damage.
Besides security processes, blast mitigation systems can be applied to columns, beams, and walls. If the facility uses explosive materials, blast mitigation systems can also be applied to the walls. Likewise, they can also be applied to the roof panels to mitigate the risk of a blast. The best ways to reduce the risk of a blast are to use a comprehensive risk assessment and implementing a plan based on the findings.
When planning a new building, blast mitigation should be a central consideration. This means that a building’s perimeter should be designed with an expert in the field. The building should be designed in such a way that it will be able to prevent the explosion and minimize damage caused by a detonation. Further, the perimeter should be a place where the blast can be confined. There should be no barriers to entry and exits.
Blast mitigation techniques are applied to buildings and infrastructures where the potential for a blast is greatest. The process of building a blast-proof structure should be centered on safety. Similarly, security measures should be incorporated into the design of the building. This will ensure that the building is as safe as possible. A building that is built with proper safeguards will prevent any damage it may cause to the community and to the environment.
During construction, physical measures can be applied to minimize the impact of a blast. The building should be designed with security in mind, and any existing infrastructure must incorporate the appropriate blast mitigation systems. This will reduce the risk of a blast. A good way to reduce the damage caused by an explosion is to prevent it from happening. This should be considered when planning any building, including a commercial building. Once the design is complete, it is important to ensure the safety of the building and the lives of those in the building.
In addition to using blast mitigation techniques, building owners should consider the physical measures that are available to them. These include building hardening materials and structural measures, such as concrete. In addition, the Blast Mitigation techniques should also consider the flying debris that may be produced by a blast. These can be applied to the walls, columns, beams, and roof panels. The building’s design should be such that it is protected from any type of debris that may be dispersed by the blast.
Among the physical measures to minimize the effects of a blast, the use of barriers, and the use of security personnel can reduce the damage caused by an explosion. Besides preventing a blast from occurring, these measures include the installation of blast mitigation systems on walls, columns, beams, and other structures. They can also be applied to roof panels and other parts of the building. The aim of the process is to reduce the impact of an explosion.
PAXCON is a revolutionary new Blast Protection Coating that helps buildings to withstand bomb blasts. Tests by the U.S. Government show that a one-eighth-inch layer applied to the front and back surfaces of a material reduces the stand-off distance by 50% or more. The U.S. Navy Base and several buildings throughout London are also protected by PAXCON. These building materials are designed to withstand high-energy explosions and incoming missiles and other types of munitions.
Polyurea is an ideal material for blast mitigation because it offers a high level of protection when applied. This protective coating is highly resistant to fire and withstands intense blasts. It is also suitable for structural steel that is under construction and should be protected from damage. The best coatings are available in the market and should be sourced from a trusted source to make sure that they are safe and effective. However, many industrial facilities may not have the resources to apply these protective layers.
Despite the high cost of polyurea, the advantages of this protective coating cannot be underestimated. It has proven to be a good choice for buildings that are subjected to frequent explosive events. For example, PAXCON by LINE-X, a division of IXS Coatings, has undergone rigorous testing to ensure its durability. The polyurea layer is so effective that it has prevented the collapse of buildings that were previously built with conventional materials.
Polyurea is an excellent material for blast protection. It is an excellent solution for concrete structures. It has high-impact and low-friction characteristics. It is a highly durable material that can protect the structure from damage. This coating can be applied to most types of structures, including buildings, vehicles, and even vehicles. Its high tensile strength and hardwearing surface ensures that it will be long-lasting and provide effective protection against a variety of attacks.
The polyurea coating applied by GLS Coatings Ltd. prevents internal walls from being fractured by impact from projectiles. The polyurea coating can be applied to concrete and metal structures and prevent structural fractures from occurring. By dissipating the impact force, the polyurea coating can reduce casualties and reduce property damage. Therefore, it is a good choice for buildings. But what is Blast Protection Coating?
Polyurea is a polyurea coating used to prevent blasts. Its flame retardant properties make it an excellent choice for buildings and other structures. Further, the coatings are compatible with a wide variety of substrates. Its use in military settings is increasing, while its application in high-profile buildings and armored vehicles is in high-risk locations. These types of Blast Protection Coating can help prevent serious physical and mental trauma.
Blast Protection Coating can help protect structures against the destructive effects of blasts. Unlike uncoated concrete blocks, polyurea is more resistant to blasts. This coating is applied on the exterior and the interior of concrete block walls. The polyurea coating can be applied to any part of the structure, including the interior. The best-fitting material is the one that is durable and resistant to damage. It is recommended for use on concrete blocks.
There are many benefits to blast mitigation. It is a powerful barrier that helps reduce casualties and property damage from hostile attacks. In addition to its anti-bombing properties, polyurea is the best material to use in bomb mitigation. Besides reducing the risks, polyurea is an excellent barrier for building components that are susceptible to the destructive effects of explosives. It is an effective and efficient solution for many types of hostile explosive attacks.
Various types of Blast Protection Coatings can protect buildings from a plethora of threats. The polyurea coatings are commonly used in a wide range of applications. The polyurea coatings are applied to buildings and concrete structures. This is an excellent option for high-profile buildings and armored vehicles. The polyurea coating dissipates the force of an explosive impact, preventing internal wall fractures.
There are many different types of Blast Protection Coatings on buildings. These coatings offer a variety of benefits, and each is uniquely designed to meet a specific need. They are often designed to withstand explosives that can cause huge explosions. They can also be applied to structures that are susceptible to explosions. When applied properly, these protective coatings can effectively shield a building from the destructive forces of an incoming bullet.
Blast Mitigation is a critical part of protecting a structure from damage caused by explosions. The system applies protective coatings to walls, columns, beams, and slabs. The coatings are also commonly used on roof panels and can be applied to the sides of a building. Generally, the protective coverings prevent flying debris and glass particles from damaging the structure. While blasts cannot be stopped, they can be mitigated.
A blast may cause bodily injury ranging from a few minutes to several minutes. It can also destroy a fixed obstacle. In addition, it can be very difficult to mitigate the impact of a blast. Many companies and organizations have implemented measures to minimize the impact of a blast. The use of security processes and background checks can minimize the risk. Regardless of whether a blast was caused by an accident or a deliberate act, blast mitigation should be a priority for any organization.
Besides physical mitigation, buildings and structures can also be hardened. For example, in the Nashville bombing, the standoff distance between the bombers and the buildings was so short that they could be easily identified. This stands-off distance is a critical part of blast mitigation. However, this can be very expensive and difficult to achieve. For high-risk targets, additional blast mitigation countermeasures may be necessary. For example, reducing the level of vulnerability can reduce the risk of a major incident. Such measures can also protect a national facility from damage.
In addition to physical blast mitigation measures, organizations can implement security processes and procedures to protect their premises from attacks. For example, they can set up safe perimeters and conduct background checks to reduce the risks of malicious acts. By incorporating these strategies, organizations can protect themselves from the worst of these threats. It is important to prioritize the safety of people and property and take steps to minimize the risk of a blast. If you do not implement any of these measures, you will endanger your business.
The techniques used in blast mitigation include physical measures such as blast barriers, crowd control, access control, and video surveillance countermeasures. Large vehicles can be screened for explosives, while fixed obstacles such as petrochemical plants can be blown apart by explosions. Using these methods to mitigate the effects of a blast is necessary for a variety of reasons. The first step is to make sure the structures are built as strong as possible.
In addition to physical measures, a blast is not limited to the building that is hit. It can affect surrounding areas as well. For instance, a building that is more than ten blocks away will be impacted by broken glass and other materials. Similarly, a building that is a few blocks away will sustain significant structural damage. Some buildings may even collapse due to the blast. The safety of the buildings and people in a structure is essential in a blast.
Physical measures include crowd management processes and operational procedures. Using security personnel is crucial to minimize the threat of a blast. There are several other ways to mitigate a blast. For example, you can use crowd control technology. You can also deploy trained security personnel to monitor the building. Often, these countermeasures can reduce the damage caused by a blast. Aside from physical barriers, there are also other countermeasures available.
Many industries utilize blast mitigation techniques in the event of a blast. The most susceptible facilities to blast damage are buildings that deal with explosive materials, such as chemical and biological weapons. Some examples of these types of structures are airports, government buildings, large commercial buildings, and petrochemical plants. Using blast mitigation methods can help ensure the safety of these structures and their employees. You should always ensure the safety of those working in the building by implementing proper security measures.
Physical measures such as barriers, video surveillance, and crowd management processes can mitigate a blast. You can also deploy trained security personnel and conduct background checks. While you can’t prevent a blast, you can reduce its impact. By limiting the risk of a blast, you can minimize damage. The best way to reduce the risk of an explosion is to build a bomb-proof barrier. This can greatly increase the odds of success.
Blasts are devastating events that can cause tremendous damage to both people and property. In order to ensure the safety of the people in these buildings, the best way is to use a blast protection coating. These coatings have been used for decades and have helped to protect many buildings. The U.S. government and several top government facilities are currently protected with these protective coatings. Besides these, there are many other benefits of blast protection coatings as well.
Polyurea is an effective protective coating for concrete structures. It has proven its effectiveness by reducing the impact of blasts on buildings and other structures. One study used polyurea to protect a military office building. This study involved the use of dummy equipment, a real bomb made of 10 lbs. of C4 and TNT, and a realistic military office environment. The results were glaring and showed that the polyurea-coated structure protected the people inside the building.
A recent study conducted by Polyurea Review showed that the coating significantly reduced blast damage to concrete structures when compared to a control group that did not. The study included two identical concrete structures, one coated with polyurea, and a military office with dummy equipment. The explosions were simulated with TNT and 10 lbs. of C4. The results of the test were dramatic. Despite the apparent disadvantages of blast protection coating, polyurea is the best option for many industrial and commercial applications.
A polyurea blast-resistant coating can protect buildings and structures. The US Marines chose polyurea because it was a better choice for the Humvees. It can deflect blast fragments, which cause the most injuries and deaths in explosions. In a high-explosion, the explosion fragments cause most of the damage. A 5mm-high hard steel Humvee door prepared according to industry standards was coated with polyurea and a protective lining.
Various coatings are available in the market. Polyurea is a polyurea coating that can resist blasts from varying distances. The product has the capacity to absorb the blasts, and thus mitigate the damage they cause. It can be applied to steel and concrete structures, and it can also protect against heat and cold. The polyurea is a self-stratifying polyurea coating that has flame retardant properties.
A polyurea coating is a good choice for concrete walls. It can be used to protect against the impact of explosives. In some cases, polyurea coatings can help mitigate mild traumatic brain injury. For other applications, it may be necessary to use a special type of blast protection coating. For example, a self-stratifying polyurea coating can reduce the chances of a structural fracture. The application of blast-resistant polyurea is recommended for structures with a high-risk of being struck by explosives.
Elastomeric polymers have been tested by the U.S. Government for their ability to mitigate blasts. The PAXCON coating was the only one to pass all bomb blast tests and is now being used on buildings around the world. Its benefits can be seen by both users and the public. This product is a great choice for ensuring the safety of buildings. And it is available in many different types. If you’re looking for a high-quality elastomeric coating, make sure to ask for a consultation with the experts at ArmorThane.
For example, a polyurea coating can protect a building from blasts. It can help prevent the structural fractures caused by blast fragments. Moreover, the polyurea coating helps dissipate impact force and prevent structural fractures. Hence, the US Marines have chosen the best protection solution for their vehicles. The United States military has a high-quality and durable polyurea coating for their Humvees.
The polyurea coating can be used for blast mitigation. Its self-stratifying property helps the polyurea coating to disperse the impact force. Furthermore, it can mitigate mild traumatic brain injury. The best protection material should have the following characteristics. It will also prevent internal and external wall fractures. Further, the polyurea coating can protect structures from the effects of the impact. So, you’ve got a blast-resistant product in hand!
Blast mitigation systems are a way to minimize the effects of a blast, such as flying glass and debris. In addition, they can help prevent collapse of buildings. By improving the surface of these structures, blast mitigation systems also act as corrosion control measures. Though these countermeasures are not foolproof, they can greatly reduce the amount of damage caused by blasts. This is especially important for high-risk targets, such as hospitals, nuclear reactors, and other critical infrastructure.
Besides developing and installing protective measures, organizations can also implement security processes. For example, establishing a perimeter around their facilities and ensuring background checks are conducted on employees can significantly reduce the risks. While it is impossible to prevent a blast from occurring, organizations should make blast mitigation a priority. Here are some tips on how to mitigate the impact of blasts. These methods will help protect your building and the lives of your staff.
Firstly, it is important to protect against blast overpressure. Explosions can cause a variety of damages, including the destruction of buildings. For example, a bomb can cause a rupture in an eardrum and cause lung damage. A secondary fragment can also cause severe injury, and is often unprotectable. Similarly, structural collapse is a common result of blast damage. In such a case, the explosion pressure exceeds the strength of the building’s constituent parts.
Secondly, blast hazards can extend beyond the blast site itself. These can affect buildings up to a few blocks away. Even buildings located more than a few blocks away from the blast site can sustain damage to their structures. Some buildings were completely destroyed. In some cases, the blasts caused an implosion or explosion that swept through the area. This makes it crucial to minimize the risk of a blast. So, if you’re planning a building, consider blast mitigation.
Physical measures are also important. While blast mitigation isn’t a replacement for effective security, it is an essential part of any building project. For example, the blast damage caused by a bomb can be felt in buildings up to 10 blocks away. However, it can also affect buildings that are further away from the blast site. Therefore, it’s essential to assess the impact of a blast and prepare accordingly. This can be done by conducting a thorough risk assessment of the building in question and identifying possible threats that can lead to an explosion.
While the threat of a blast may seem remote, it is essential to consider the consequences of such a blast. If a blast causes damage to a building, the resulting structural collapse may cause it to collapse. Fortunately, there are many ways to mitigate the damage caused by a blast. One of the most effective ways to protect against a blast is to ensure that the entire structure is protected against any potential threats.
As a general rule, the most effective blast mitigation techniques are a combination of physical and operational measures. In addition to physical measures, there are also operational procedures and crowd management processes. A well-built building is more likely to withstand the blast than one that has a low-quality structure. In many instances, physical safety solutions are not sufficient. In such cases, a disaster response team is needed. The corresponding disaster response will include identifying potential threats and the damage to the building.
While there are a number of ways to mitigate a blast, some of the most important methods are: – physical measures. The simplest and most effective of these methods involves the use of a standoff distance. By minimizing this distance, the risk of a blast is minimized. In addition to physical measures, people and assets may also be protected with the use of special equipment and trained security personnel. In the worst-case scenario, there is a blast that causes structural damage, which requires the deployment of an immediate countermeasure.
As a general rule, blast mitigation is a vital component of any building design. In particular, a building’s perimeter should be carefully designed to minimize damage caused by a detonation. For more complex buildings, the protection of the entire building can be achieved by employing a number of different techniques. In a public building, the risk of a blast can be minimized by a blast. If it is possible, the area should have a safe standoff distance.
Blast Protection Coatings are designed to minimize the effects of explosions on buildings and structures. The U.S. Government has been testing elastomeric polymers for their impact-resistant properties since 1996. The first one to pass all blast mitigation tests was called PAXCON, and this coating is now being applied to many buildings around the world, including the U.S. Pentagon, the Federal Court House in New York, the Washington Naval Base, and several buildings throughout London.
A polyurea coating is used to protect concrete block walls. The application of the polyurea coating prevents shattered blocks and reduces the impact force on internal walls. However, this coating does not prevent internal fractures resulting from projectile impacts. It also deflects the blast fragments, which are responsible for the majority of injuries and deaths from explosions. This technology also helps prevent structural fractures by reducing the energy of impact on the building’s materials.
The impact force generated by an explosion can cause the front of a concrete block to shatter, causing a fracture in the inner wall. A polyurea coating helps to keep the front of the wall solid and prevents this. It also dissipates the impact force and prevents internal fractures. This is important in protecting critical infrastructures in a hostile environment. In addition, polyurea is also effective in absorbing shock waves.
A new material called polyurea has been developed for blast mitigation applications. This revolutionary new material was commercialised in the late eighties. It is made up of a polyurea that resists massive pressure. Because of its unique characteristics, it is a good choice for high-profile buildings and armored vehicles. It is also highly resistant to impact, and it is used in high-security military installations. The material is also available in many colors and textures.
Blast protection is a critical element in military operations. The material itself has many advantages. It is a strong and durable material that can withstand explosions. The coatings on buildings and structures can withstand a blast equivalent to a car bomb. It also dissipates impact force and keeps structures in place. It is widely used on the Pentagon and other high-profile government facilities. These materials are also safe to the environment, and they can protect your employees and clients.
Applied to buildings and structures, blast mitigation coatings can dramatically reduce the amount of property damage and casualties that result from explosive attacks. The sprayed-on polyurea coatings can prevent structural damage, and reduce the impact of flying debris. Ballistic protection coatings are especially useful for high-profile structures such as the Pentagon and government buildings. They can provide the protection needed to protect from blasts and ensure that the building remains in place.
The coatings are applied to the exterior of buildings. The US Marines, for example, use polyurea on their Humvees to protect the interior from IEDs. The polyurea coatings on the walls can prevent internal wall fractures and dissipate impact force. As a result, these protective coatings are effective in preventing internal and external wall fractures caused by explosives. So, what are you waiting for? The best Blast Protection Coatings are waiting for you!
This coating has numerous benefits. It can minimize the damages caused by hostile explosive attacks. Its polyurea coatings are made of an elastomer that can withstand enormous pressure. This coating is an excellent choice for armored vehicles and high-profile buildings. If you’re concerned about blasts, consider installing a Blast Protection Coating to protect your building. The advantages outweigh the disadvantages!
The US Marines wanted to add extra protection to their Humvees to protect against the effects of IEDs. They installed a protective liner called Dragonshield-HT (r) ERC. This material has the power to disperse a blast fragment without damaging the front of a structure. It also helps deflect and contain the impact force. For example, the coatings can protect from IEDs and reduce the damage caused by a terrorist attack.
PAXCON is an excellent choice for buildings to protect against explosions. This coating is a polyurea or polyurethane-based coating. Its flexible nature and high-strength properties make it a great choice for protecting against a blast. Further, PAXCON is much stronger than steel and is flexible. The material will flex during an explosion and not crack, which will increase the impact resistance of the building.
For years numerous companies and governments around the world have tried to come up with better ways to protect human lives and physical property from blast threats.
The damage caused by blasts/explosions and the resulting energy shock waves can cause devastating losses. Modern chemistry and the innovative R&D team at ArmorThane have produced several solutions to help provide blast protection and combat these tragic events.
“Protecting the protectors”
ArmorThane’s ArmorBlast ultra high strength Polyurea coatings provide superior blast mitigation and ballistics protection to military and civilian entities around the world.
ArmorThane originally developed these groundbreaking polymer coatings for the United States military. After years of R&D and continual improvement of the technology, ArmorThane is proud to offer industry, cutting-edge, blast resistance solutions that help save human lives and protect property.
Blast and explosion mitigation has come a long way from thick concrete and metal housings. New research into granular-filled panels and metal foams has taken the spotlight in some material research circles, but these energy dissipative techniques can be disruptive to the structure or system that is being protected.
Explosion and blast mitigation has advanced from the thick concrete and metal housings. The latest research on granular-filled panels as well as metal foams has been able to grab the spotlight in certain research groups, however, these methods of dissipating energy could cause disruption to the structure or system protection.
The Office of Naval Research, since 2000 and continuing to fund research to create strong, blast-reducing solutions for ship hulls following attacks on the USS Cole. The focus of the research was ways to prevent rupture due to an underwater explosion that was close to the surface.. The result was the development of the high tensile strength and weight-to-weight ratio polymer, which was given the name Energy/Explosion Resistant Coating or ERC.
ArmorThane ArmorBlast Protected Wall
To the left is an image from a demonstration by ArmorThane of a polyurea coating applied to an unconstructed block of concrete. The front side of the wall was covered with ArmorBlast and the backside was left untreated. The uncoated blocks were able to break and throw projectiles but the front was solid. If it is applied on the whole wall the internals could break but the wall will remain in place and the force that was emitted by the impact will be extinguished.
Alternatives for ERCs are available now and are generally constructed from identical polyurea, polyurethane, or in combination with other techniques to mitigate blasts. The claims are that a wall coated with ERC (such as ArmorBlast, Defend-X, and a variety of other coatings for blast mitigation) can withstand forces of explosion as high as 20 times the force of that of a comparable, uncoated wall. It can be utilized alongside concrete, wood brick, steel as well as other materials for structural engineering in both military and commercial applications.
An even more amazing demonstration of an ERC coated brick wall, a cinder block as well as a control wall, both of which were hit by a realistic car bomb blast. The inside view of 1:10 shows walls expanding inwards, but is held in its ERC coating.
Watch how the combination consisting of polyurea as well as Kevlar sheet can stop this cinder block from being blown up by an explosion. The blast was large enough to resemble the typical car bomb. It was the left wall that had been left unfinished as designed to serve as the control wall. The right side was coated with polyurea
The ONR after 9/11 increased its research efforts to include protection from ballistic penetration as well as land mines and IEDs that were improvised (IED) and blasts. The polymer was incorporated into vehicles for troop transport and multi-purpose use. From this point, spray-on variations that made use of ERC polymer were created and were later widely used.
If a hyper-intelligent car is your main tool for thwarting criminals, it is vital that it be bulletproof or your career may be cut short. Although you don’t want heavy armor panels to stop your hyper-intelligent vehicle from being super-fast and high-performance.
The latest version of the Knight Rider car solves this problem using nanotech magic. However, the original Knight Rider used a bullet-resistant coating. This was the formula for some of their most memorable episodes (The Goliath episodes).
Although science took another 15 years to develop the bullet-proof coating, ArmorThane was able to make it a reality with their polyurea protective coating. ArmorLiner, their latest advanced and innovative variant of this coating product is a spray-on polyurea coating that makes walls virtually indestructible. Once applied they become bullet/blast resistant and ready to take on any situation.
It was tested by the U.S. Air Force on a typical quicky-build military structure. They were amazed at how well it held up to explosions. Polyurea could not be damaged by the 1,000 pounds of TNT that were required to do so.
Smash Lab, a Discovery Channel program, tested a polyurea coating on two trucks. One truck had the coating, and one did not. (Although Rhino Liner is a competitor to ArmorThane, it is very similar in chemical makeup.) They then set off five pounds worth of “industrial explosives” underneath the truck’s rear axle. The truck-bed that was left uncoated was shredded and scattered across the desert test site. The liner deflected the blast to the front of the truck and destroyed the cab. It makes sense to coat KITT with the stuff and have a bulletproof car. You can paint over it to give KITT a sleek and shiny appearance.
ArmorLiner is opaque so traditional bulletproof windows will be required. Then there is the issue of the underbody. It is easier to repair cars that are open at the bottom. Coating every part of the car’s bottom would require cutting through the material every time an item needed to be repaired or checked. It is more likely that KITT has a large metal shield running along the underbody. Sarah Graiman and Bonnie would need to take it off in order to make repairs. When fixing-it scenes are being shot, I imagine that a long shielding piece shaped like KITT is leaning against the wall. It’s possible that Billy will knock it over.
Show News: Knight Rider’s future has been covered in a lot of news lately. The show was first picked up for a full season. After that, the entire season was cut by four episodes. NBC also decided to eliminate three characters: Carrie Rivai and Alex Torres. Future episodes will bear a closer resemblance with the original series, where KITT assists in finding terrorists and criminals. Although it is not clear whether the show will be canceled, there are some signs.
People have tried to protect themselves against projectiles for centuries. This evolved from Hand-held shields made from stretched leather and wooden frames to complete wooden shields. Eventually to full steel shields, combine with chain-mail body armor, specialty woven silk fabric, and finally to specialty metals. As the speed and type of projectiles used have changed so too has combat with the use of BODY ARMOR.
The type of protection required was based upon the type of projectiles that were delivered. These were initially clubs or handheld spears, with developments later that would project an object through mechanical means, such as hand-drawn bow and arrow or mechanical crossbows. Currently protection is based upon projectiles delivered at very high velocity through handheld devices commonly referred to as firearms. For reference, the average speed of sound is 1126 feet/sec.
Protective armor can be made from a variety of polymeric materials. Components and structures that are shrapnel or blast-resistant. Materials like ceramic plates, ultrahigh molecular weight polyethylene (UHMWPE), and poly-aramid are all commonly used. These are also known as “KEVLAR“, and polymeric matrixes that have fiber-reinforced structure, made from one or more of the above-mentioned polymers have been shown to exhibit ballistic dampening.
These are some of the characteristics. Figures 2, 3 & 4 show examples of current armor systems. This protective type of soft armor was first developed in 1943 and was called “The Protective Type Soft Armor”. A “flak jacket”, to reduce the effects of shrapnel and wounds, was used during World War II. With much Development was completed, and the late 1950’s saw the introduction of soft armor protection. However, it was heavy. As the Vest M-1951 or the Armored Vest M-1955. Protective vests could be combined Layers of poly-aramid fabric, and composite plates made from compressed fiberglass laminates. The Doron Plate. Figure 1. Cartridge Comparison L. to R.:.22LR,.380 ACP. 9 mm.45 ACP..357 Magnum..44 Magnum. 5.56X45mm, 7.62X35mm, 7.62X51mm Figures 2, 3, & 4 L to R: Soft Armor and Composite Armor.
Figure 5 shows an example of the M-1955 vest. Figure 5. M-1955 Armored Vest Possessing positive physical and performance characteristics, but not limited to High strength-to-weight ratios and high impact resistance. These materials can be subject to shock loading. These include Flaking and surface chipping can make them friable. It is also hard to make a durable. These materials can be protected with a protective coating or an aesthetic long-lasting finish. These drawbacks are especially noticeable in applications like the production of blast Location of shrapnel armor in different wear and traffic areas, such as the floors Wall regions and aircraft of various motorized vehicles. Panels and other constructions Attached to the vehicle structure are pieces made from suitable armor material They provide protection for the occupants. These panels provide armored protection that is more than adequate.
The materials are vulnerable to wear such as chipping, flaking and gouging as well as items like Ordinance-related cargo and ordinance-related items can be dragged or dropped onto panel surfaces during routine usage Operation These materials can be difficult to paint on or coat because of the lower adhesive. The panels are made of polymeric materials that have certain characteristics.
It would be ideal to create a coating composition that can be used to coat at A friable substrate should not have more than a small portion of its surface. A coating is also recommended It can be used to cover a substrate and stick to it. It would It is also desirable to have a coating composition that adheres well to the substrate With challenging adhesion properties. It would be nice to apply a coating Without unduly compromising, composition that can be used with an armor panel The panel’s blast or ballistic resistance.
You can achieve armor protection by using different layers of UHMWPE and/or Polyaramid fiber sheets Type IIA requires approximately 18 sheets. Type II at 21 sheets, and Type IIIA with 35 sheets or layers. It is interesting that soft armor can be found in both Type IIA with 21 sheets and Type IIIA at about 35 sheets or layers. Panels are sold as backpack inserts and brief cases for students. Protective coatings for play Plural-component polyurea elastomeric technology (PUA), was created after the spray application.
A variety of applications were demonstrated when the technology was introduced in late 1980s. Although most of the applications are related to protective coatings, there are some other areas. One Spray applied technology was used to create shooting targets (called “Ivan’s”) for the purposes of the US Military Training.6 To produce a variety, the elastomeric Polyurea system was applied to an open mold. For military training exercises, the polyurea was used to create and “human-form” targets. The polyurea was used at Dry film thickness (DFT), 125-250 mils (3.1-6.4 mm). These polyurea targets can be shot at Complete penetration was observed in Type IIA-Type IV classifications (from Tab 1) The projectile. Multiple shots are possible due to the elastic properties of the polyurea. The target was not significantly damaged. There was no stopping power for the projectile. The polyurea produced an interesting result with the holes “resealing” themselves. Later, chopped aramid fiber was introduced to the polyurea spray pattern. System to ensure true ballistic properties.7 – 8.
Figures 6 and 7 illustrate the effects of aromatic polyurea on entry and exit points of a panel. At a DFT of approximately 250 mils (6.4mm).
Recent work has produced the same results that was seen in the 1980s. To help, the polyurea system could also be used on existing steel components in military vehicles. The polyurea does not reduce the effects of small arms fire and blast shrapnel, but it is NOT BULLET. PROOF! 9 – 13 The polyurea alone would not be enough to stop bullet travel. It can be applied to a thickness well above 1 inch (2.54 cm), which adds considerable dimension and weight.
A 1 ft2 polyurea piece (0.1 m2) of 1-inch thickness would be over 5.5 lbs. Kilograms This illustration was made using different thicknesses of an aromatic polyurea (elastomer) to illustrate the point. Impact from projectiles listed in the NIJ Classification Table I. An 80 mil Layer (2 mm) was exposed to three rounds with a Type I Classification.22-cal projectile (Type I Classification). The polyurea was heated to 80° F (27° C). The same procedure was used on a similar piece at 6oF (-15oC). To show the PUA’s flexibility at low temperatures, These are shown in Figures 8 and 9. Figure 8 and 9. It was used. 14 The hard system (Shore D50) showed cracking due to the high velocity impact. area, while the soft system (Shore A80) did not. This is quite normal given the High velocity projectile
Protecting the “Plates”. Given the above discussion, and the fact that polyurea is not bulletproof by itself, where do we go from here? Technology fit? Most ballistic plates consist of soft armor made with polyaramid fibers. Composite pieces made of steel, ceramic, or fiber must be protected against any damage. It will be ineffective. Ballistic plates are subject to bullet fragmentation. injury or plate shattering following multiple hits. The polyurea coating system applied to the plate is not recommended. The ballistic part is not to be used, but to trap bullet fragmentation and protect the plates resulting injury or damage.15 The 1950’s Flak Jacket, as mentioned earlier, contains both rigid and soft armor.
The rigid armor consisted of the 130 mil (3.35 mm) Doron plates, which were encased with nylon and cotton fabric. Place in the pockets of the vest by rapping. Rapping serves two purposes: Trapping projectile fragments. Encapsulating the ballistic panel in a Trapping material isn’t a new idea. Figure 10 illustrates the fabric-encapsulated plate. Figure 11 shows the same plate after an impact with a Type IIIA projectile. This is the case. .45 ACP, the common round for that era. The fabric panel, as seen, is efficient, but significant. Panel damage is noted.
A 10″ X10″ test panel of polyurea-protected UHMWPE composite panels was used to demonstrate the effectiveness. (25.4 cm X 25.4 cm) Composite panel of overall A thickness of 20mm was subjected 3 rounds 7.62 rifle caliber projectile. The 20 mm plate It was made up of 18mm thick UHMWPE. Encapsulated in 40 mils (1mm) of polyurea Each projectile contained 155 grains (10g) With a velocity of 2000 feet/sec (610 meters/sec), Energy of 1365 ft.lbs force (1850 Joules). This This is a Type III (rifles), classification All 3 rounds were contained within the composite panel. The first 1/4 inch of total panel thickness is included with no Complete penetration The entrance hole is in the polyurea coating was 2 mm thick. The backside The impact was achieved by bulging the panel. The applied polyurea coating has been damaged. The effectiveness of the following figures is shown in the following series of graphs This polyurea composite panel is made from a bullet Nature is proof.
What happens when a projectile of high velocity impacts a hard-ballistic plate? The projectile Completely disintegrates and will splatter high-velocity shrapnel at 90 degrees (perpendicular). The direct area of impact. The shrapnel can travel at high speed and cause significant damage. Damage to the outer areas. Figures 2 through 6 show the effects of both coated and uncoated. Ballistic panels and protected polyurea ballistic panels for projectile fragmentation The “trapping” effect. Figures 19-20 show the effects of high velocity impacts on a panel made from ballistic steel. The panel He was enclosed in a “soft” zone using cardboard and paper. In Figure 20, you can see the outlying. The “soft” area can be completely cut using a sharp knife or, more descriptively, a buzzsaw. To minimize or eliminate shrapnel dispersion from projectile impacts The ballistic panel and the application of an eleastomeric, tough polymer system such as polyurea Spray coating can be used. This coating can be applied in a variety of thicknesses, depending on the application. Depending on the NIJ classification level. The shrapnel effect will be dissipated by this layer. You can even trap it completely. Figures 21-22 show the effects of projectile impact upon a polyurea-coated ballistic panel. It is important to note that there was no shrapnel splash (Figure 21), and that the projectiles were fully trapped Figure 22: Between the coating layer (Figure 22) and the ballistic panel
As mentioned previously, the polyurea technology has an unexpected advantage over the ballistic work of 1987. After the projectile passes through, the elastomeric properties of the System allowed for penetration to reseal. This has a fascinating lubricating effect. The projectile’s polymer is an important feature in normal coating and liner work. The coating may be punctured by nails or bolts in some cases. This reduces membrane leakage. This is particularly important for common. This technology is used for waterproofing. How does this apply to ballistic applications, however? Storage tanks are often used in many cases. These tanks, whether permanent or mobile, can contain highly flammable substances. These tanks can be found in They may also be shot at in hostile areas. Although an explosion or fire is unlikely, a projectile could cause a spark that ignites the flammable fuel. Coating These structures are made with an elastomeric system of polyurea systems. The leakage is reduced and the steel is not as hot. Substrat is protected from sparking from projectiles This is illustrated by a 1/8 inch (3.18 mm), steel plate coated with about 100 mils (2.5). (mm) of an elastic aromatic polyurea system. The steel plate was prepared according to SSPCSP 5, White Metal Blast Cleaning. It has a profile of two mils (50 microns). 16 These figures show the sealing power of a polyurea system on a substrate After being exposed to projectile impact. These projectile cartridges represent the most effective. Common in hostile areas (Type III rifles).
The steel plate’s exit holes are wider than the actual diameter. Projectiles The applied polyurea is well bonded to steel around it. hole, and “re-sealed” the projectile entry hole. A device was attached to the back of the panel made from steel in order to test the sealing ability. Exit hole. The fluid was then introduced to the device and pressurized to determine the desired pressure. Pressure to demonstrate fluid leakage at the projectile entry area (Figure 28). The liquid used At 77oF (25oC), the viscosity was 1 centipoise, 1 millipascal. These Results are listed in Table III.
Polyurea is not a product, but a technology. Like other coating technologies, polyurea is a technology. There is no “one-size fits all” solution for polyurea technology. There are two types of basic systems for this area: one that provides ballistic trapping effects and one that allows for the Sealing effect. The general characteristics of both systems are shown in Table IV.
CONCLUSION This paper demonstrates how protective coatings such as polyurea elastomer can be applied. Coating technology can provide personal protection. Polymeric composition Systems can be used in a wide range of coating applications, including those with friable and easily combustable materials. Materials with poor adhesion properties and substrates that are damaged may be rejected. Particularly, The compositions shown here are materials that can be used for blast resistance coatings These panels are shrapnel-resistant and can be used for other purposes. This world is becoming more violent. It is vital to protect our military, law enforcers, and citizens. Protective coatings This area is dominated by polyurea technology. Before you make a decision, however Spray yourself with polyurea. But remember that polyurea is not bulletproof by itself!
Major corrosion problems faced by Amphibious Assault Vehicles (AAVs) in the United States Marine Corps could be solved with polyurea.
As the U.S. Marine Corps looks to extend the AAV, Dr. Mike Roland and Dr. Ray Gamache of the U.S Naval Research Laboratory (NRL) have led a study project into how best to shield and prolong the life of these armored vehicles.
Like those NRL is investigating, innovative sustainment concepts enable them to avoid the cost of new design, development, and production of new components. Since the 1990’s the U.S. Marine Corps has been using bolted-on armor to protect their AAVs. This armor is a laminate of high hard steel, rubber, and soft steel coating in the back. The issue is, this armor gets corroded in severe conditions – including exposure to saltwater.
The corrosion starts at cracks in the paint, which happens due to expanding the different layers within the laminate – which expand and contract independently due to environmental changes.
The NRL states that polyurea will better protect the armor from corrosion by expanding and contracting with it, rather than cracking as paint does. Furthermore, polyurea demonstrated resistance to bullets and blast fragments by taking kinetic energy from the bullet.
By recreating the unique corrosion issues of the Amphibious Assault Vehicles in a lab, the team has concluded that polyurea is a much better product for protecting the armor against corrosion than paint.
“We solved the corrosion problem,” says Dr. Mike Roland of the NRL. “And with a negligible increase in weight, we also provided a higher payload capacity and the potential for better ballistic protection.”
With conventional materials, you can have something that’s stiff but doesn’t stretch much; or you can have something soft, like silly putty, and it stretches a lot. Polyureas can stretch to 10 times their original length, but the force it takes to do that is enormous—so you get extreme toughness. It truly is the best of both worlds!
