Abstract (en)

[origin: WO9310973A1] A multilayered glass laminate having enhanced resistance to spalling and penetration by high velocity projectiles consists of at least three plies of glass (10, 12, 14) with layers of plasticized polyvinyl butyral (16, 18, 20) therebetween and having permanently bonded to an outer layer of one of said plies of glass (14) a thin composite consisting of an adhesive energy absorbing layer (22) and a dimensionally stable polyester film (24).
