A method of making a composite material part, in particular a wind turbine blade of great length, consists in placing a thickness of a cloth made up of threads comprising a mixture of polypropylene threads or fibers and of glass fibers or threads in two mold portions having the shape of the part that is to be made, placing an inflatable envelope on the cloth inside one of the mold portions, in closing the mold, in placing it in an enclosure fed with hot gas under pressure to melt the polypropylene of the cloth, thereby embedding the glass fibers or threads, then in allowing it to cool, and in unmolding.
