Abstract:
1. A method of fabricating a lug on a structural element of composite material, said structural element being made from a pattern presenting two opposite edges cut out from a fiber fabric made up of superposed primary plies bonded together in such a manner that the plies can slide relative to one another, said pattern having at least one extension for forming the lug, the method including rolling the pattern into a tube to form a body of the structural element in such a manner that the primary plies slide relative to one another to give a chamfer shape to the two edges, the chamfer-shaped edges being joined so that they overlap, the method further including separating the primary plies in the at least one extension, inserting intermediate plies between the primary plies, and piercing the at least one extension to produce a lug.
