In many movies, we often see the "bulletproof" glass, bullets do not penetrate. Is there really a bulletproof glass in the world? If so, how is it bulletproof? Today, let us come together to talk about it. From the appearance, bullet-proof glass and ordinary glass is no different. However, this is only their only similarities. A piece of ordinary glass, as long as a bullet can be crushed. The bullet-proof glass, according to the thickness of glass and shooting weapons of different, can withstand a hair to several rounds of ammunition attacks. So, why  bullet-proof glass can resist bullets?

Bullet-proof glass  capability depends on the thickness of the bullet-proof glass.For example,Rifle bullets impact the glass intensity is much larger than the pistol bullets, so the bullet-proof bullets rifle bullets than only the bullet-proof bullets bullet defense glass to be much thicker.There is also a one-way bullet-proof glass. One side of it can defend the bullet, but does not prevent the bullet from the other side through. This allows the attacked person to fight back. The bulletproof glass is a layer of brittle material and a layer of ductile material laminated.

Imagine a car equipped with this one-way bulletproof glass. If someone outside the car to the window shooting, the bullet will first hit the brittle material layer. The brittle material in the vicinity of the impact point becomes crushed and absorbs part of the energy over a wide range. The resilient material absorbs the remaining energy of the bullets to resist the bullets. A bullet fired from the inside of the same vehicle can easily penetrate the glass. Because the energy of the bullet hit in a small area, making the resilient material shells. This in turn causes the brittle material to crumble outwardly, thereby allowing the bullet to penetrate through the ductile  material, hitting the target.
