摘　　要：高性能热塑性复合材料具有高韧性、优异的抗冲击损伤性能及较佳的抗疲劳性能,特别适用于以起落架、尾段、桨毂中央件及传动轴等为代表的直升机高损伤阻抗、高抗疲劳及弹击损伤容限设计需求特定结构部位。高性能热塑性复合材料在国外直升机上的应用正从实现关键层板结构部位全面应用拓展至复合材料夹层结构部位,并大量采用原位自动纤维铺放(automated fiber placement,AFP)等自动化、低成本制造技术和虚拟实验等低成本验证技术,受限于国产热塑性复合材料技术成熟度较低和新研复合材料体系传统积木式方法应用验证的高昂成本及漫长周期,国内直升机热塑性复合材料应用尚处于起步阶段,未来需要重点解决国产热塑性复合材料的性能稳定性及一致性以及在此基础之上的低成本自动化制造工艺、配套低密度耐高温芯材及高效率高置信度虚拟认证技术。High-performance thermoplastic composites,due to their high toughness,excellent impact damage resistance and better fatigue resistance,are especially suitable for constructing special helicopter structures such as the landing gear,tail section,rotor hub and transmission drive shaft,which requires high damage-resistant,ballistic-tolerant,anti-fatigue properties.The application of highperformance thermoplastic composites in foreign helicopters is expanding from the application of key laminate structures to honeycomb sandwich structures,and a large number of low-cost and auto-mated manufacturing techniques such as in-situ automated fiber placement(AFP)and low-cost verification techniques such as virtual testing is being used.Limited by the low level maturity of domestic thermoplastic composites technology,high cost and long cycle of the traditional building block verification methods for the new composite system,the application of thermoplastic composites in domestic helicopter is still in initial stage,the performance stability and consistency of thermoplastic composites,supplementary low cost automatic manufacturing process,low density and high temperature core material and high-confidence efficient virtual qualification technology are needed to focus on the future.
