Composite structure which is used for the embodiment of the pieces obtained by a method of moulding by injection under vacuum and / or infusion

摘要

The present invention relates to a composite structure used for the production of parts obtained by a method of moulding by injection under vacuum and / or infusion. It relates to the field of the molding technique known under the name rtm for resinetransfert moulding.selon the invention, the composite structure comprises a complex textile reinforcement (3) intended to be impregnated with a hardening agent, characterized by the fact that the said textile complex (3) is arranged with a complex of overlap (4) comprising an outer skin of the finish (40). the outer skin of the finishing operation is thus directly incorporated into the structure before molding so that a finished part may be obtained directly after the mold.
