This method is directed to provide an improved bond between the metal reinforcement and a composite material, notably at a node comprising the connection between walls and a flange of composite material. It comprises essentially the steps of incorporating a metal reinforcement in the form of an assembly of three elements, namely a first element in the form of a hollow cylinder having a relatively broad base and connected to the flange, a second element capping the first one and provided with fins extending along the walls to be connected to the flange, and a third intermediate element consisting of a washer interposed between the first and second elements so as to distribute the fin pressure over the base surface.
