Abstract:
1. A method of fabricating a composite part presenting a structure of composite material comprising at least one reinforcing layer based on reinforcing fibers, fabrics, or textiles, and at least one impregnation matrix (R, R 1 , R 2 ), the method comprising assembling the structure, in placing said structure in a mold, in impregnating said structure with the impregnation matrix (R, R 1 , R 2 ) by injection or infusion, and in solidifying said impregnated structure by raising it to a determined temperature, the assembling comprising: using at least two distinct primary parts for making up an integral structure; and placing a thermoplastic sheet on at least one of the primary parts or in between the primary parts so as to make an interface of the integral structure; wherein the thermoplastic sheet presents thickness lying in the range 0.02 mm to 1 mm and the materials constituting the thermoplastic sheet include at least one material that expands under the effect of heat, one of the at least two distinct primary parts is generally planar, and another of the at least two distinct primary parts has a planar base and a transverse flange.
