Composite Steel Foam Stops Bullets

Jun-07-19 A composite metal foam able to stop bullets could lighten the load on the military and police forces.

Led by Afsaneh Rabiei, a team from North Carolina State University developed the bulletproof material by embedding steel spheres inside the steel matrix of the composite metal foam. This steel-steel CMF was then placed between a ceramic faceplate and a thin, aluminum back plate, resulting in an armor plate strong enough to absorb up to 78 percent of the kinetic energy from armor-piercing rounds.
