Features For example, the use of some bank bulletproof vehicles has promoted the invention of one-way bulletproof glass. This glass will resist the outer side of the small weapon firing glass, but will allow shooting on the opposite side (back side) of the glass, such as a defender shooting from the inside of the armored car, thereby shooting through the glass to the outside threat on. principle One-way bulletproof glass is usually made in two layers: a fragile layer on the outside and a flexible layer on the inside. When a bullet is fired from the outside, the bullet will hit the fragile layer and break an area. This will absorb the kinetic energy of some bullets and spread kinetic energy in a larger area. When the slowed bullet hits the flexible layer, it is blocked. However, when the bullet is shot from the inside, it will hit the flexible layer first. Bullets can puncture a pliable layer because its energy is concentrated in a small range, and the brittle layer shatters outward when the flexible layer bounces outward, and does not hinder the progress of the bullet. Bulletproof glass is a glass that has the ability to protect the bullets while having the light transmission and transparency properties of the glass. The bulletproof principle of bulletproof glass is that it can convert the impact kinetic energy of the bullet into the elastic potential energy of the glass and the surface energy of the debris.
