Scientists at North Carolina State University have released a video showing lightweight metal foams turning an armor-piercing bullet into dust on impact.
In this video, composite armor made out of the composite metal foams (CMFs) stop a 7.62 x 63 millimeter M2 armor piercing projectile, which was fired according to the standard testing procedures established by the National Institute of Justice (NIJ).
‘We could stop the bullet at a total thickness of less than an inch, while the indentation on the back was less than 8 millimeters,’ said Afsaneh Rabiei, a professor of mechanical and aerospace engineering at NC State, who has researched the development of CMFs and investigating their unusual properties. ‘To put that in context, the NIJ standard allows up to 44 millimeters indentation in the back of armor.’
