Protection principle of bulletproof glass

- Apr 24, 2018 -

In bomb attacks and accidental explosions, the anti-bomb glass can minimize direct damage caused by blast shock wave ultra-high loads and high-speed splashing of glass fragments, and reduce the repair costs of the attack facilities or facilities around the explosion center. The anti-bomb glass maintains a non-penetration under the condition that the load formed by the explosion shock wave energy increases rapidly and increases several times or even several dozen times, and the glass retentivity value RET≈1. However, once the monolithic glass (including float glass, tempered glass, and hollow glass) is broken, RET quickly drops below 0.3 below the critical crushing pressure, and the glass fragments scatter, causing penetrating damage.
