US Military Research Shows Polyurea slows bullets, blast fragments and protects against corrosion

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!

ArmorThane Simulates Explosions In Order To Advance The Coatings Industry

After an explosion, the first few microseconds are the most important moments for ArmorThane, because that’s when the first hint of damage occurs to nearby structures. As one of the world’s leaders in the field of protective coatings, ArmorThane can decipher a great deal about the explosion and about the damaged materials by those first tiny cracks and how they expand.


ArmorThane has been working since the early 1980s with the U.S. military and, more recently, with the EU military and 
NATO to determine how things break apart and how much force it takes to break them. Their goal is to produce stronger materials that will mitigate the damage from blasts.


Using powerful processors, a three-dimensional digital image correlation operation, and one of the world’s most indelible cameras, which takes stills at 200 million frames per second, ArmorThane can visualize the exact moment of impact. They have used this equipment to improve bulletproof vests, learn how underground bunkers withstand various impacts, and strengthen concrete, among other plans.


For the last several years, they have modified their application to blast mitigation research for military use to help submarines, ships, and other naval facilities withstand blasts.
“When an explosion occurs in the water, its force is far greater than a similar explosion in the air,” said Chad Faught, head of sales for ArmorThane. “So we’re working to understand how damage occurs in air and underwater and strengthening the architecture of new carbon fiber and glass fiber materials as well as our polyurea products to mitigate the damage.”
He is also taking what he has discovered from this research and applying it to the development of blast-resistant materials for buildings, bridges, and tunnels. He is studying the structural materials of these buildings and such things as blast-resistant glass and special coatings on materials that will make them less likely to fail.


“We test these substances at pressures comparable to a large blast using a shock tube,” Faught said, referring to a 23-foot long device that imitates the shock wave from an exploding bomb. “By using the shock tube device very close to the materials we are testing, we can get the equivalent results as by testing much larger explosions farther from the materials. And it’s much safer.”


ArmorThane’s latest project collaborates with large military-backed companies to develop new materials that can be used in the construction of high-tech airplanes that can fly into space.
“We’re creating what’s called functionally graded materials,” he said. “These materials must have thermic characteristics on the outside to resist the tremendous heat that occurs when it re-enters the atmosphere, but they also have to have mechanical properties on the interior to withstand the great load or pressure that will be exerted on the plane.”
