摘要
为满足高推重比航空发动机在长时热力氧化环境下的使用需求和航空发动机关键热结构部件的隐身需求,碳化硅陶瓷基复合材料正朝着自愈合抗氧化、兼具承载和吸波性能的结构吸波一体化发展。本文分别介绍了碳化硅陶瓷基复合材料在强韧化、自愈合抗氧化、电磁波吸收三方面的设计原则,综述了在这三方面的研究现状。一种材料同时具有高强度高韧性、自愈合抗氧化和吸收电磁波三方面的性质将是结构功能一体化CMC-SiC未来发展的大趋势。
In order to meet the need of high thrust ratio aero engine working in long term thermal oxidation environment and the stealth requirement of key thermal structural components of aero engine,silicon carbide ceramic matrix composites are developed towards crack self-healing and structure-wave absorbing integration.In this paper,the design principles of silicon carbide ceramic matrix composites in strengthening and toughening,crack self-healing and electromagnetic wave absorption are introduced.The research progress in these three aspects is reviewed.The future development trend of structural and functional CMC-SiC is the combination of high strength and toughness,self-healing antioxidation and electromagnetic wave absorption.
