Abstract

The present invention concerns processes for making composite materials. The process is characterized essentially by the fact that it consists in making a fibrous preform 1, in pre-treating this fibrous preform by a fluorine containing flux 3 and in wetting the said pre-treated preform by a light alloy. Utilization for the making of composite pieces with a fibrous armature such as carbon wet by a light aluminum-based alloy.
