How does bullet proof glass work? how is some glass bullet proof and some isn’t? is there different types of glass on a molecular level? (not sure if physics is the accurate flair)
In: Physics
Bullet proof glass is often laminated of layers of glass and special plastic. The glass layers are hard and act to deform the bullet, while the plastic layers tend to stretch and absorb the energy of the bullet. There are different degrees of “bulletproof-ness,” depending on the number of layers and materials used. Some will stop small caliber pistol bullets, and some will stop large caliber rifle bullets. If you shoot enough bullets at the glass, eventually it will be defeated, but the idea is that it will last long enough for the person behind it to escape or return fire.
