To meet the long-term use requirements of high performance aero-engine in high-temperature gas environment, SiC-based self-healing ceramic matrix composites (SHCMC) are developing towards the oxidation resistance in high-temperature water vapor environment. This paper firstly clarifies the structural design principles of SHCMC based on the application requirements of it. And the great challenges faced by SHCMC at present were also introduced in detailed. Based on those, some progresses in SHCMC from high temperature stability of self-healing glass phase were reviewed in this paper. The SHCMC with self-healing ability in wide temperature range under the condition of water vapor conforms to the future development trend.
