Abstract
Method for producing a fibrous reinforcement (1) for a component of composite material comprising at least two non-coplanar walls, which are for example orthogonal. According to the invention, at least one first fibrous element (2) is produced as a fiber mat, said first fibrous element (2) is applied via one of its narrow sides (4) against a first face (5) of a second element; and there are inserted, through a second face (7) of said second element (3), on the opposite side to said first face (5), and by the stitching without knotting of a continuous filament (F) by means of a needle, transverse fibers passing through said second element (3). Production of fiber-matrix composite components.
