Bulletproof glass?

What makes bulletproof glass bulletproof? is it just layers of glass piled on top of each other with some kind of polymer/fancy-shmancy thing mixed in with it too?

    Different manufacturers make different variations of bullet-resistant glass, but it is basically made by layering a polycarbonate material between pieces of ordinary glass in a process called lamination. This process creates a glass-like material that is thicker than normal glass. Polycarbonate is a tough transparent plastic — often known by the brand name Lexan, Tuffak or Cyrolon. Bullet-resistant glass is between 7 millimeters and 75 millimeters in thickness. A bullet fired at a sheet of bullet-resistant glass will pierce the outside layer of the glass, but the layered polycarbonate-glass material is able to absorb the bullet’s energy and stop it before it exits the final layer

    Bulletproof Glass is usually constructed using a strong but transparent material such as polycarbonate thermoplastic or by using layers of laminated glass.The polycarbonate layer, usually consisting of products such as Cyrolon, Lexan and Tuffak, is often sandwiched between layers of regular glass. The use of plastic in the laminate provides impact-resistance, such as physical assault with a hammer, an axe, etc. The plastic provides little in the way of bullet-resistance. The glass, which is much harder than plastic, flattens the bullet and thereby prevents penetration. This type of bullet resistant glass is usually 70-75 mm thick.Bullet resistant glass constructed of laminated glass layers is built from glass sheets bonded together with polyvinyl butyral or polyurethane. This type of bullet resistant glass has been in regular use on combat vehicles since World War II; it is typically about 100-120 mm thick and is usually extremely heavy

    well it is all about nano technology. they try to put the atoms so close together to make it as strong as posible, then they layer them to make it reinforsed.

    Its designed to take the impact force of the bullet, and absorb the force rather than reject it.The bullet then becomes lodged in the layers.

    What they do is make layers of thin glass, between each layer is a layer of clear plastic. Many layers of glass and plastic. When a bullet hits, each layer of plastic it goes thru, slows it down. So before it can come out of the other side, it has completely stopped. Bullets flatten like a mushroom so there is more width to slow down.

    Bullets that are made from grinding down a single piece of metal, such as a steel bar, will go thru any bullet RESISTANT glass. They do not call the glass bullet-proof. For insurance reasons.

    yep. Layers of tough polymers and glass.

    Call Kenny at Kenny’s Glass Works 330-659-4377 (local from Cleve) He is located in Richfield/Bath. I bought Lexan from him before. Real good guy. He will guide you in the right direction. Lexan does scratch easily but I’ll bet you could cover it with glass or Plexiglass for protection.

    look up Lexan or call DuPont

    Don’t have a real answer for you. Glass is what it is…Lexan is plastic and has a stopping power that is unmatched. It is however very expensive and gets dulled after many cleanings.
