Metal Foam Stops Speeding Bullet

Metal foam tough sufficient to turn an armour-piercing bullet into dust could be used to create the following generation of body and vehicle protection.

A team at NC State Univ discovered that an inch-thick layer of composite metal foams (CMFs) can stop a bullet.

The indentation on the back of the foam is just 8mm - significantly less than the 44mm allowed by the US National Institute of Justice.

Video of one of the university'south tests shows the bullet hitting a target marked on the material.

But instead of piercing the metal foam, the bullet instead appears to disintegrate on impact.

CMF is a type of material created by incorporating hollow beads of one metal into a substrate cast from another.

Despite a low density, it boasts impressive physical characteristics.

Latest year, the team showed that CMFs are highly effective at shielding X-rays, gamma rays and neutron radiation.

They also handle fire and heat twice as well as the plain metals they're made of.

As a result, the applications for the material don't just stop at combat situations: it could've uses in everything from space exploration to nuclear waste containers.
