An impact resistant transparent panel (10) has a plurality of first layers of glass (12, 14, 16) for retarding the passage of a ballistic such as a bullet. A second layer (26, 28), preferably epoxy based resin, disperses the energy of the ballistic. A backing layer (30), preferably polycarbonate, inhibits passage of fragments. A method for forming the panel (10) by pouring the second layer (26, 28) in liquid form and curing it is also disclosed. The panel inhibits the passage of ballistics from an attack side (42) to a defence side (40) while allowing passage of ballistics from the defence side (40) to the attack side (42). |
