To the embodiment of an armature of fibers for a piece of composite material has walls that are not coplanar, and a composite comprising such a reinforcement piece.

摘要

- process for the production of a fibrous reinforcement (1) for a composite material comprising at least two walls that are not coplanar, for example orthogonal. & br / - according to the invention, at least a first fibrous element (2) is made of a mat of fibers, said first fibrous element (2) is applied by one of its edges (4) against a first face (5) of a second element, and is introduced, through a second face (7) of the said second element (3), opposite to said first face (5), and by stitching, without knotting a continuous yarn (f) with the aid of a needle, the transverse fibers passing through said second element (3). br / - production of composite parts fibers - matrix.
