Abstract
A laminated environmental protective layer for acrylic aircraft windows provides significant improvement in the performance of original production windows and in repair of damaged aircraft windows. A thin chemical and erosion resistant outer protective layer of environment resistant transparent material is laminated to the exterior acrylic surface of the aircraft window using a thin urethane interlayer. Use of chemically strengthened glass for the outer protective layer and hot processing of the laminate increases impact resistance. Addition of an inner balancing layer minimizes bowing of the processed window and enhances stiffness of the window and compression of the outer layer for additional impact resistance.
