abstract Ceramic matrix composites (CMCs) are non-brittle structural ceramics for application at high temperatures. They consist of ceramic fibers embedded in a ceramic matrix, the fiber/matrix bonding being controlled through weak enough interphase. CMCs are processed following gas, liquid or powder routes. Their main properties are presented and discussed, including mechanical behavior, thermal conductivity, dimensional stability, friction and the effects of an oxidizing atmosphere or nuclear radiations. Finally, the applications of CMCs are briefly presented in rocket motors, spacecraft thermal protection, aerojet engines and cogeneration gas turbines, braking systems and high temperature nuclear reactors.
