Fabrication of Fire Resistant Transparencies

Abstract

Describes methods of casting sheets, curving the sheets into the required contours and then laminating the epoxy transparencies to other plastics. Laminated side windows were made with epoxy as the outer surface and polycarbonate as the inner surface. Identical sized windows were also made using a single cast monolithic sheet of EX-112. Tests of the composite transparencies consisted of ballistics tests, determination of heat distortion temperature, limiting oxygen index, buring rate, thermal conductivity and the coefficient of thermal expansion. Results indicated a substantial improvement in fire resistance over state-of-the-art acrylic transparencies.
