Abstract:
1. A system comprising: a coupling made of composite material comprising a polymer matrix reinforced by a fiber structure, said coupling comprising: an adjacent part including a mating surface, wherein matrices of said structural layer and of said first machining layer are identical, wherein said first machining layer is situated on at least a fraction of a main face of said structural layer, and is machined so as to present a first machining exterior surface with fibers which have been cut, wherein there is no intersection between said first machining exterior surface and fibers of said main fiber structure, wherein the first machining exterior surface of the first machining layer is machined to correspond to the mating surface of the adjacent part, and wherein the structural layer is not machined to correspond to the mating surface of the adjacent part.
