As for making anything bulletproof? Not going to happen. Much like idiots, they just build better bullets. My guess? Anything AP or over .50cal goes RIGHT through this stuff.

The bullet was an armor piercing round. Here's the detail of the test:

"The shield was comprised of boron carbide ceramics as the strike face, with composite metal foam (CMF) as the bullet kinetic energy absorber layer and Kevlar panels as backplates. To test its durability, Rabiei and her team took aim with a 7.62 x 63 mm M2 armor-piercing projectile, which was fired in line with 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 mm," Rabiei says. "To put that in context, the NIJ standard allows up to 44 mm (1.73 in) indentation in the back of an armor."

Lightweight metal foam turns armor-piercing bullets into dust
