A WINDOW PANEL

摘要

A lightweight impact-resistant window panel, for example for adhesive glazing to the airframe of an unpressurized aircraft, has outer and inner glass plies which are laminated with an intermediate impact-resistant plastics ply. An inner ply of impact-resistant plastics is bonded to the rearward face of the inner glass ply. The aggregate thickness of the impact-resistant plies is in the range from about 1 mm to about 7.5 mm.
