Abstract

The invention relates to light-type bulletproof airplane windshield glass. The light-type bulletproof airplane windshield glass is formed by combining a tempered glass layer, a PC (poly carbonate) board material layer and a wear-resistant coating from outside to inside sequentially by bonding materials. The airplane windshield glass provided by the invention is light in weight but high in intensity, completely meets the design requirement on light weight of an airplane, has good bulletproof performance, is high in interlayer bonding intensity, is free of interlayer peeling after being impacted, prevents problems of layering, air bubbles and the like, and is low in specific gravity and low in thickness; the bulletproof performance of the windshield glass meets the relevant requirements of F79H level of GB17840-1999 bulletproof glass, and the light-type bulletproof airplane windshield glass is suitable for airplane equipment such as light-type fighters.
