How about a lightweight body armor one inch thick that can not only stops but disintegrates a 7.62X 63 mm M2 armor piercing bullet.

Afsaneh Rabiei, professor of mechanical and aerospace engineering at N.C. State, has spent several years developing CMFs and investigating their unique properties.
The bullet used in the demonstration video is a 7.62 x 63 millimeter M2 armor-piercing projectile, and was fired using standard testing procedures established by the Department of Justice for evaluating armor types.

The armor — only an inch thick — features a ceramic strike face, Kevlar backing, and CMFs in the energy-absorbing middle layer.
“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,” Rabiei writes in press materials issued with the video.
