Patent ID: 8518518

Claim:
A fiber structure that can be embedded in a matrix for obtaining a piece made of composite material, whereby said structure comprises: a first fiber element ( 12 ) that comprises a first support surface ( 18 ); at least one L-shaped fiber element ( 20 ) comprising a base that is flattened against said first support surface ( 18 ) of the first fiber element ( 12 ) at a junction zone ( 22 ) and a wing that is not flattened against said first fiber element ( 12 ); and another fiber element of which one part is flattened against the wing of said at least one L-shaped fiber element ( 20 ), said elements assembled by tapping fibers ( 26 ) from the second surface ( 28 ) of the first fiber element ( 12 ) in such a way as to form loops, at least certain fibers ( 26 ) being oblique relative to the surface ( 28 ) of the first fiber element ( 12 ), in a plane that is perpendicular to the junction zone ( 22 ), wherein certain loops of said oblique fibers ( 26 ) protrude to the outside of the outer surface of the wing ( 20 . 2 ) of the at least one L-shaped fiber element ( 20 ).
