摘　　要：热塑性聚醚醚酮(PEEK)复合材料具有优异的断裂韧性、抗冲击性能、耐疲劳性能,广泛应用于航空航天领域。上浆剂作为碳纤维的核心配套产品,对复合材料界面有重要影响。受分解温度限制,传统热固性碳纤维上浆剂难以满足PEEK复合材料使用,制约高性能PEEK复合材料的研制和应用,因此研制匹配PEEK复合材料的碳纤维上浆剂具有重要意义。本文分析了PEEK复合材料界面特性及上浆剂作用机理;重点介绍了改性PEEK、聚酰亚胺前驱体、聚醚酰亚胺等类型上浆剂的研究进展和成果,并对不同体系上浆剂进行分析总结;最后对PEEK复合材料用碳纤维上浆剂的研制提出建议,对上浆剂绿色环保多功能化趋势进行了展望。Thermoplastic polyether ether ketone(PEEK)composites are widely used in aerospace field due to their excellent fracture toughness,impact resistance and material versatility.Sizing agent as the core auxiliary product of carbon fiber has an important impact on the interface of composites.Limited by the decomposition temperature,the traditional thermosetting sizing agents are difficult to meet the use of PEEK composites,which restricts the development and application of high-performance PEEK composites.Therefore,it is of great significance to develop a matching carbon fiber sizing agent for PEEK composites.In this paper,the interfacial properties of composites and the action mechanism of sizing agent were analyzed and introduced;the research progress and results of modified PEEK,polyimide precursor and polyetherimide sizing agents were focused,and different systems of sizing agents were analyzed and summarized.Finally,the relevant suggestions on carbon fiber sizing agents for PEEK composites were put forward while the environmental and multi-function developments for sizing agents were prospected.
