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.
