Windscreen safety glassIn 1937, in Britain, safety glass for windscreens was made mandatory in new vehicle manufacturing. It was known that in car accidents, ordinary glass would break into dangerous, jagged blades. Safety glass was made as a sandwich of clear, flexible plastic laminated between two layers of glass. When French artist and chemist Édouard Bénédictus first patented safety glass in 1909, the choice of plastic was limited to a sheet of clear celluloid. He discovered the idea by accident in 1903. During WW I, it was used in the eyepieces of gas masks. By 1936, others plastics had become available, of which polyvinyl butyral (PVB) was adopted because of its strength and ability to stretch making it the most safe and effective to use. Such safety glass when struck could merely bulge, or break into less harmful pieces.«[Image: modern safety glass in a windshield split, but not into dangerous shards, by the passenger's head when the car crashed into a large tree.] |
