Glass fiber reinforced high-performance thermoplastic composites have the advantages of impact damage resistance, high toughness, electrochemical corrosion resistance, low cost, etc. They have been applied and developed in the aviation fields such as civil aircraft, military transport aircraft, etc., in recent years. In this paper, the application examples of glass fiber reinforced high- performance thermoplastic composites in the aviation field abroad were summarized, and the gap between raw materials and composite manufacturing technology at home and abroad was analyzed. The apparent mass and mechanical properties of HS6 high- strength glass fiber reinforced poly (aryl ether ketone) thermoplastic prepreg prepared were compared with those of S2/PEEK prepreg of the same type abroad. Through comparison, it is found that the impregnation quality and mechanical properties of domestic prepreg still have a certain gap with those of foreign countries, and the preparation process of prepreg needs further exploration and improvement.
