ASSEMBLY OF FIBROUS ELEMENTS FOR OBTAINING A PART MADE OF A COMPOSITE

摘要

The subject of the invention is a fibrous structure that can be embedded in a matrix in order to obtain a part made of a composite, said structure comprising: a first fibrous element (12) having a first face called the bearing face (18); at least one L-shaped fibrous element (20) having a portion called the base, said portion being pressed against said first bearing face (18) of the first fibrous element (12) in a junction area (22) and another portion, called a flange portion, not pressed against said first fibrous element (12); and another fibrous element, one portion of which is pressed against the flange of said at least one L-shaped fibrous element (20), said elements being assembled by the stitching of fibres (26) from the second face (28) of the first fibrous element (12) so as to form loops, at least certain fibres (26) being oblique to the face (28) of the fist fibrous element (12), in a plane perpendicular to the junction area (22), characterized in that certain loops of said oblique fibres (26) emerge on the outside of the external surface of a flange of at least one L-shaped fibrous element (20).
