Bulletproof glass is a type of strong but optically transparent material that's specifically proof against being penetrated when struck. it is a glass that's ready at stopping all forms of main factors fired at it. like several material, however, they aren't totally impenetrable. this sort of glass is made by using the usage of a robust but clear subject material such as polycarbonate thermoplastic. every now and then it’s made by the usage of layers concerning laminated glass.
it is usually constituted of a mixture of two or extra varieties of glass, one exhausting and one smooth. The softer layer makes the glass more elastic, so it might flex instead of shatter. The index of refraction for both of the glasses used within the bulletproof layers have to be nearly the same to maintain the glass transparent and allow a transparent, undistorted view throughout the glass. Bulletproof glass varies in thickness from three-quarter inch to three inches (19mm to 76mm).
every other construction means is the usage of safety laminates as a movie on the internal floor of unusual glass. This, when bonded with the appliance of a force delicate adhesive and cured fully, additionally gives a protection just like the multi-layered bullet-resistant glass. The optical clarity is significantly better and tint-free, thickness and weight are decreased as much as 50–70%, and the method will also be accomplished as a retrofit on present home windows.
Bulletproof glass is often referred to as ballistic glass, clear armor or bullet-resistant glass.
