What's bulletproof glass?
Like any material, struck. Like any material, however, it is not completely impenetrable. It is usually made from a combination of two or more types of glass.

Laminated glass layers are built of layers of glass sheets bonded together with polyvinyl butyral, polyurethane, Sentryglas or ethylene-vinyl acetate. When treated with chemical processes, the This is definite thick and is always extremely heavy. This design has been in regular use on combat vehicles since World War II.

How does the bulletproof glass work
More correctly cal led bullet-resistant glass, it's made from multiple layers of tough glass with "interlayers" of various plastics. Sometimes, there's a final inner layer of polycarbonate or plastic film to prevent "spalling When. This bulletproof glass, its energy spreads out sideways through the layers. Because The bullet slows down so much that it no longer has enough energy to pierce through-or to do much damage if Think of bulletproof glass as "energy-absorbing" glass and you have a good idea how it works.

How to make bulletproof glass
To make simple PVB film based on bulletproof glass, the thin PVB film is sandwiched between the thicker glass to make a laminate, which is heated and compressed so the plastic melts and begins to bond to the glass. Often this process happens in a vacuum to prevent The main difficulty with the process is ensuring that the plastic and glass layers stick together properly with no air trapped between them, and ensuring the autoclave's heat and pressure does not distort the plastic so it too difficult to see see through

Where is the bulletproof glass used for
Generally speaking, the thicker the glass and the more layers it has, the more energy it can Basic bulletproof glass ranges from about 3 cm to 4 cm thick, but it can be made with twice this thick if necessary.
