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 .
