Ceramic matrix composite (CMC) materials offer unique design possibilities for their superior thermo-mechanical properties. There are several manufacturing techniques to produce CMC. Reaction bonding is illustrated in this paragraph. Reaction-bonded CMCs with the larger amount of publications and industrial applications are silicon carbides (RBSiC) and silicon nitrides (RBSN) composites. After years of research work, mostly in the aeronautical and aerospace sectors, there are several applications of these composite materials. As a sort of follow-up of many years of basic and industrial research, RBSiC has found its way to industrial markets thanks to the friction components. Nowadays RBSiC composites are a standard in high performance braking systems for racing and sport cars. Further work is ongoing trying to protect these materials against active oxidation and to increase their upper temperature working limit by using, during melt infiltration, silicon alloyed with other metals. RBSN presents outstanding thermo-mechanical properties but, for their applications in oxidative environments, they need to be coated with environmental barriers.
