摘要
高性能热塑性复合材料具有高韧性、高耐温性、良好的抗疲劳和耐腐蚀性,以及可回收再利用的独特优势,近年来在大型民航飞机、直升机、发动机等航空领域均取得广泛的研究和应用。随着航空发动机不断追求更高推重比,对新材料的需求更为迫切,热塑性复合材料以其独特的性能优势成为制造航空发动机短舱结构的理想材料。介绍了国外高性能热塑性复合材料预浸料研发、先进制造工艺的发展现状及其在航空发动机短舱结构上的应用情况。同时,对比了国内热塑性树脂性能、预浸料制备工艺以及复合材料成型工艺方面与国外存在的差距。
Thermoplastic composites(TPCs)have been widely applied to commercial aircrafts and helicopters because of their good toughness,heat resistance,fatigue strength,chemical resistance and recycling for recent years.With regard to aircraft engines,there is an even more urgent demand for high performance materials to achieve higher thrustweight ratio.Thus,TPCs are the ideal materials to manufacture aero-engine nacelles.This article introduces foreign developments on prepreg research and advanced manufacturing process of high performance TPCs,as well as,whose applications on aircraft engine nacelles.Meanwhile,domestic developments have also been contrasted in thermoplastic resin properties,prepreg preparation and manufacturing process of TPCs.
