Is the bulletproof glass really bulletproof

   As a special bulletproof glass, many people have questions and concerns about whether it can bulletproof. Today we will explain this issue from two aspects of the specifications and principles of bulletproof glass.

Bulletproof glass specification

   Bulletproof glass is a type of laminated glass. Laminated glass is a layer of non-glass material between two pieces of glass. Their structure is similar to that of a hamburger, with a layer of beef between two pieces of bread. Structurally, bulletproof glass is no different from ordinary laminated glass. The main difference between bulletproof glass and ordinary laminated glass is the material of the two pieces of glass and the material of the laminated glass. At present, all manufacturers of bulletproof glass in the world mainly use two kinds of interlayer materials on bulletproof glass, one is called PC full name is polycarbonate polymer plastic, and the other is called PVB full name is polyvinyl butyral polymer plastic. Butyraldehyde polymer plastic. Among the two, PC is more common than PVB ( an interlayer used in laminated glass).

Bulletproof glass working principle

   Strictly speaking, there is no completely bulletproof glass in the world. Bullet-proof glass is more accurately called: bullet-resistance glass. When we test the bulletproof function at a specific angle, designed distance, and the bullet type, at the corresponding bulletproof level, the front side of the bulletproof glass is damaged, but the back side is not penetrated. This is because bulletproof glass changes gravitational potential energy to elastic potential.

Is the bulletproof glass can really bullet

    Well, bulletproof glass can indeed be bulletproof. But this must be based on the same bulletproof level. What we must know is that although bulletproof glass can be bulletproof, if the machine gun keeps firing, I think it may not be able to withstand the pressure, so bulletproof glass is not necessarily very safe.
