Raleigh, NC, United States (4E) – There’s a chance the next generation tank that will replace the storied M1 Abrams main battle tank (MBT) might be protected by a new and incredibly tough armor called Composite Metal Foam (CMF).
In addition to its ability to defeat anti-tank rounds or anti-tank guided missiles, CMF also pulverizes these armor piercing projectiles. CMF is also far lighter than the heavy Chobham armor plates protecting the Abrams and the popular rolled homogeneous armor steel plate protecting other tanks. This special type of armor foam has the potential to reduce the weight of armor on combat vehicles by as much as 65 percent.
Tests conducted by North Carolina State University and the U.S. Army’s Aviation Applied Technology Directorate also prove that CMF provides better protection from explosive blast waves, deadly “cook-offs” that result from the explosion of tank rounds inside a tank and radiation.
CMF is a spongelike material riddled with small spheres, or holes, that give it the appearance of Swiss cheese under magnification. When an anti-tank round strikes a CMF, the foam’s hollow spheres absorb some of the kinetic energy from the round’s impact and prevent further damage to the armor from the hit.
Tests have shown CMF can provide enhanced protection from heat. This slow transmission of heat can help save lives, especially in conditions that might lead to ammo cooking-off inside the tank. CMF can greatly slow down the transfer of heat to explosive ammunition.
