摘要
连续纤维增强陶瓷基复合材料由纤维、陶瓷基体和界面三元素构成。由于其具有密度低、耐高温、抗腐蚀、抗辐照、强度高等特点,且在断裂过程中表现为非脆性断裂特征,因此成为一类重要的结构材料,在一些极端服役环境中体现出不可替代的发展趋势,备受世界各国关注。近20多年来,欧美、日本等发达国家一直将陶瓷基复合材料的研发作为重点研究方向,并投入巨资进行研究。针对新一代高推重比航空发动机热端结构、高超声速飞行器热防护结构以及新一代核能系统结构部件对适用于极端服役环境陶瓷基复合材料的需求,结合目前的研究现状,从组成、结构设计和制备的角度浅析适用于不同服役要求的陶瓷基复合材料的构建,为材料在极端环境下的性能优化提供借鉴。
Continuous fiber reinforced ceramic matrix composite （CMC） consists of fiber, ceramic matrix and interphase. It is a kind of promising material that can be used under extreme environment due to its low density, heat resistance, corrosion resistance, radiation resistance and high strength. Ceramic matrix composite has been drawn much attention and intensively studied by western countries. In order to meet the application requirements of ceramic matrix composite served as thermal-structural materials in extremely severe environment, such as new generation turbine engine, hypersonic vehicle and new generation nuclear fusion reaction, the design of CMC was discussed, based on the composition, structure and fabrication process. This review is expected to give suggestive guidelines for the performance optimization of CMC under extreme service conditions.
