当使用具有层状结构或微观结构的界面相（如焦碳、hexhex - bn或（SiC-PyC）n多层）来控制纤维-基体结合时，SiC-SiC复合材料表现出非脆性行为。当界面的裂纹挠度和载荷传递函数达到平衡时，材料的力学性能达到最佳。SiC-SiC复合材料对氧化非常敏感，但可以通过调整其组成和微观结构来提高其在氧化气氛中的稳定性。
SiC-SiC composites exhibit a non-brittle behaviour when the fibre-matrix bonding is controlled by the use of an interphase with a layered structure or microstructure, such as pyrocarbon, hex-BN or (SiC-PyC)n multilayers. The best mechanical properties are achieved when there is a balance between the crack deflection and load transfer functions of the interphase. SiC-SiC composites are sensitive to oxidation but their stability in oxidizing atmospheres can be improved by tailoring their composition and microstructure.
