连续纤维增强 SiC 基复合材料界面相力学及抗氧化改性研究进展

The mechanical and oxidation resistance modification effects, the related influencing factors, and the shortcomings of pyrocarbon （PyC） and its derivatives, BN and its derivatives, new style interphases, and compound interphases were reviewed, and several common interphases preparation technologies were also briefly compared. Among them, the PyC interphase had excellent mechanical modification but no oxidation resistance, and adding B element was still difficult to overcome its intrinsic oxidation resistance. The comprehensive performance of BN interphase was preferably good, but brittle at medium temperature and was not moisture-proof. Lots of advantages of composite interphase were presented, but the problems such as mismatch of thermal expansion coefficient and poor chemical compatibility can not be ignored. The new interphase was hard to be considered in terms of properties or preparation methods. The future development direction is to improve the performance database and damage mechanism, to explore more new types of interfacial phases, and to tap the potential of existing interfacial phase preparation processes.
