Laminated glass: Sheets of glass fibre fabric or glass wool are soaked in a solution of a thermosetting plastic and placed one above other, the thickness varies with number of sheets, and the laminated sheets are then cured under heat and pressure. After curing, a hard, light and strong laminated sheet is obtained. This is as strong as steel and three times lighter then steel. It is non-flammable and insulating. The laminated glass can be used for:

(1)         Making light weapons

(2)         Insulating materials

(3)         It is shatter proof, when suddenly broken; its pieces do not fly off.

(4)         It is shock proof and can withstand by pressing together several layer of glass with vinyl resins in alternate layers. The thickness of bullet resistant laminated glass generally varies from 12.7 mm to 76.5 mm and these are prepared for specific purposes.
