Abstract: The invention relates to a method comprising a step (E0) of forming a body provided with a cavity on a face of said body, a treatment step (E2) consisting of forming, on said body, at least one reinforced adhesion area which is at least partially outside the cavity, and a step (E3) of depositing composite material. During the deposition step (E3), the cavity is filled and the reinforced adhesion area is covered with the composite material.
