Abstract: A method for producing, by welding, a joint between a thermoplastic matrix composite material and an elastomeric material. The elastomeric material is functionalized by incorporating, onto the surface of the elastomer, a nonwoven fabric consisting of fibers of thermoplastic material. The functionalized surface of the elastomeric material is welded to the thermoplastic material of the composite. The functionalization of the elastomeric material is performed during the vulcanization of the raw elastomer. The vulcanization is performed under a sufficient pressure for the nonwoven fabric placed on the surface of the raw elastomer to become incorporated with same, at least at the surface, during the vulcanization process. The welding operation includes interposing a metal fabric coated with thermoplastic material between the surfaces of the elastomer and the composite that are welded to each other, and passing an electric current through same, resulting in the surface melting of the two materials.

Abstract: A method for producing, by welding, a joint between a thermoplastic matrix composite material and an elastomeric material. The elastomeric material is functionalized by forming a thin layer of elastomeric material incorporating particles of thermoplastic material and melting the thin layer onto the surface of the elastomeric material during the pressure-vulcanization of the elastomer. The functionalized surface of the elastomeric material is welded to the thermoplastic material of the composite. The welding operation includes interposing a metal fabric coated with thermoplastic material between the surfaces of the elastomer and the composite that are welded to each other, and passing an electric current through same, resulting in the surface melting of the two materials.

Abstract: The invention concerns a method for producing, by welding, a link between an element made from any material, for example metal, and an element made from a thermoplastic-matrix composite material, the second element being produced by depositing a textile yarn pre-impregnated with a thermoplastic material on the surface of the first element. The method mainly includes an operation consisting of producing an interface coating consisting of an epoxy resin filled with a thermoplastic material powder, coating the surface of the element made from any material with same, and leaving the coating to polymerize. It next includes an operation consisting simultaneously of forming the second element and welding same to the coating deposited on the surface of the first element by locally heating the two elements, when depositing the pre-impregnated textile on the first element.
