摘　　要：在高性能热塑性树脂基复合材料的开发与前沿应用中,常规的纤维上浆剂存在耐高温性能不足的问题,因此,耐高温型增强纤维上浆剂的开发与研究引起了广泛关注。基于纤维上浆剂的配方组成,介绍了近年来增强纤维用上浆剂的耐高温化改性研究进展。重点综述了耐高温型上浆剂体系中浆料树脂(成膜剂)的选择与优化方法,探讨了无机纳米杂化对上浆剂耐热性能提升及复合材料界面性能的改善效果,并分析了偶联剂在耐高温型上浆剂体系中的作用与性能。基于产业化应用的考虑,最后指出:深入分子结构设计,开发绿色环保的耐高温型上浆剂将是未来研究的重点;考虑各类纤维及树脂基体的结构性能差别,有针对性地开发耐高温型上浆体系极为必要。Significance Fiber sizing agent is one of the core technologies in the production of reinforcing fiber(carbon fiber,aramid fiber,glass fiber,etc.)and its composites.The sizing agent coated on the surface of reinforcing fibers facilitates the bundling of filaments,remedies the surface defects of the fibers,and improves the processing property of corresponding fabrics.Moreover,the sizing agent promotes the infiltration and tight binding of the matrix resin on the fibers through physical and chemical effects such as increased compatibility in similar structure,induced crystallization,and crosslinking/reaction.Nevertheless,the stability of the general fiber sizing agents at high temperatures is insufficient to meet the needs for the development and advanced applications of high-performance thermoplastic resin-based composites.Therefore,the development of fiber sizing agents with high temperature resistance has attracted extensive attention.Based on the basic composition of sizing agents,this review reports research and development progress in fiber sizing agents with high temperature resistance,which focuses on the selection and modification of film former of the sizing agents and introduces the effect of the inorganic hybridization on the heat resistance of sizing agents and interfacial properties of composites.The importance and property of coupling agents in the formulations are also discussed.Progress Fiber sizing agent is a mixed liquor composed of a variety of functional components,including film former,coupling agent,lubricant,antifoaming agent,antistatic agent,pH regulator,and other functional additives.Film former accounts for 70%-90%of the total solid mass of sizing agent which directly affects the wetting ability and compatibility of fiber in resin matrix.To meet both requirements of high temperature resistance and compatibility with the matrix,most research focuses on the development of novel film former based on polyimide and polyarylether,which show high thermal stability and the same or similar chemica
