The fabrication of high performance metal matrix composites requires the optimization of the interfacial bonding, which supposes a strict control of the reactivity and of the wettability between the matrix and the reinforcement, specially for materials produced by casting techniques. In this scope, two methods are described consisting on the one hand, in the surface treatment of carbon fibres by a particular type of CVD and, on the other hand, in modifying the composition of the matrix. The two methods can be used either separately or in combination, sucessful tailoring of the interface being the result of thermodynamic or kinetic effects.
