ABSTRACT:
The invention relates to a method for producing a reinforcement in the form of a sheet for a composite component, the reinforcement including superposed plies of thread. In accordance with the method, straight portions of thread are arranged, for each ply, at least substantially in a parallel fashion with respect to each other and all the superposed plies are consolidated by using a thread passing through the plies. According to the invention, the superposed plies are laid down on a support, the superposed plies are compacted by mechanical pressure, and in order to preserve the state of compaction of the plies which is thus obtained, the thread for consolidating the plies is stitched, without knotting, through the plies down to at least the level of the surface of the support, the plies having, after compaction, a density of the portions of the thread constituting them which is sufficient to retain the consolidating thread by friction.
