ceramic armor

Ever wonder how tank armor and armor tests worn by soldiers can be made of ceramic---even though when you drop your ceramic cup in the kitchen it shatters? Guess what? Ceramic tank armor also shatters when it is hit by a projectile. The shattering absorbs the shock and protects the tank underneath. Ceramic tank armor is in the form of plates that are attached to the outside of the tank. When one is hit, a new plate is simply attached in its place.

Ceramic armored vests are made of some material (probably largely Kevlar) with sewn-in pockets, each containing one ceramic plate. If a bullet impacts one of the plates, it shatters into pieces which are contained in the pocket. The soldier simply pours the pieces out and inserts a new plate. Cool, huh?
