摘　　要：连续纤维增韧碳化硅复合材料(CMC-SiC)热结构部件已广泛应用于航天、航空、航发领域,该部件通常采用组合装配集成制造技术研制,发展新型高性能CMC-SiC紧固件制备技术是推动部件制造技术的关键之一。本文从组装集成制造技术需求特点出发,阐述了CMC-SiC紧固件的类别、制备技术和微结构特点,分析了CMC-SiC复合材料对CMC-SiC紧固件力学性能的制约关系,总结了CMC-SiC机械连接剪切行为、钉载分配和拉伸行为的研究现状,揭示了CMC-SiC紧固件静态力学性能及其失效机制。进一步分析了CMCSiC紧固件振动松弛机制及其防松措施,探讨了氧化损伤对CMC-SiC紧固件性能的影响。据此,从预制体结构设计、制备工艺和紧固件结构角度,提出了CMC-SiC紧固件性能优化途径,最后展望了CMC紧固件制备技术及其连接性能的发展。Thermal structural components made of continuous fibre-reinforced silicon carbide ceramic matrix composites(CMC-SiC)have been widely employed in aerospace and aeronautical fields.Integrated manufacturing techniques have been also extensively utilized to assembly CMC-SiC parts together to form large and complex components.The development of novel high-performance CMC-SiC fasteners has become critical manufacturing technology.In this work,different types,preparation methods,and microstructural characteristics of CMC-SiC fasteners were reviewed based on unique demands in terms of component preparation.It is demonstrated that shear strength of fasteners was very similar to in-plane shear strength of composites.Tensile and shear behaviours,load distribution among fasteners,failure mechanisms,and oxidation damages of CMC-SiC bolted/pinned joints were summarized.Furthermore,vibration relaxation mechanism and related anti-loosening effect were discussed.Accordingly,an optimization of CMC-SiC fasteners was proposed based on fibre architecture design,preparation process,and fastener structure.In the last,the development of CMC fastener manufacturing and their joining performance was prospected.
