PCT No. PCT/FR83/00068 Sec. 371 Date Dec. 19, 1983 Sec. 102(e) Date Dec. 19, 1983 PCT Filed Apr. 14, 1983 PCT Pub. No. WO83/03625 PCT Pub. Date Oct. 27, 1983.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.
