Ceramic matrix composites

  • R. R. Naslain


SiC—SiC coposites 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.
