Abstract
Method for producing a fibrous reinforcement (1) for a component of composite material comprising a panel provided with a rib. Transverse fibers (4A) are inserted over the whole extent of the first fibrous element (2), through the opposite face of the first fibrous element (2) to the second fibrous element (3) and by the stitching without knotting of a continuous filament (4) by means of a needle (33, 40), so that the transverse fibers (4A), which are located opposite the bearing flange (3A) of the second fibrous element (3), form stitches (4B) joining the first and second fibrous elements together and that some (4A1) of the transverse fibers (4A) are located vertically in line with the stiffening flange (3B) of the second fibrous element (3). Also a method for the production of composite components of the aircraft structural panel type.
