what makes glass bulletproof

First, understand the principle of bulletproof glass, the structure of bulletproof glass, and the ballistic test standards. This will help us understand what makes glass such a fragile material easily resistant to ballistic impact. Quoting article:  bulletproof glass  How does bulletproof glass work , after understanding the principle and structure and test standards, we can know that bulletproof glass is mainly used for energy buffering through thickness and film layer to resist the bullet at the moment of penetrating the glass.

Material and function

Bulletproof glass first uses transparent glass or Polycarbonate-containing composite materials, so we can know that there is no bulletproof performance under the barrier of single-layer transparent glass. Why can multi-layer combined bulletproof glass be effective bulletproof?

The multi-layer glass structure and the intermediate film toughness can effectively reduce the energy of the bullet after passing through the film layer and the second layer of glass after penetrating the surface glass (the impact energy of specific firearms has a greater correlation). Decrease layer by layer, and finally play a ballistic performance.

PC is a polymer composite material. Under high-energy impact, its toughness is greater than that of transparent glass, and it has better impact resistance and better light transmission. Therefore, some higher requirements for ballistic performance require the use of PC to reduce glass weight and improve ballistic performance

Bulletproof glass level

Because the shooting test method is the same, different firearms affect the impact energy. Of course, the bullet weight and core material also affect the impact energy, and the shooting distance and number of shots also affect the overall bulletproof test results. Therefore, we are formulating a series of test standards and specifications based on the test process to determine a reasonable and effective grade evaluation standard. What grade of bulletproof glass has what kind of ballistic performance, of course, all test results are based on samples provided by the manufacturer

The effect of the bullet-proof glass shown in the above picture after the test is: the glass is intact as a whole, the back is raised, and the fragments do not splash or splash and do not penetrate the cardboard.
