Abstract
A fiber structure that can be embedded in a matrix for obtaining a piece made of composite material, includes a first fiber element having a first support surface, at least one L-shaped fiber element having a base that is flattened against the support surface of the first fiber element at a junction zone and a wing that is not flattened against the first fiber element, and another fiber element having one part flattened against the wing of the at least one L-shaped fiber element. The elements are assembled by tapping fibers from a second surface of the first fiber element so as to form loops, at least certain fibers being oblique relative to the second surface, in a plane that is perpendicular to the junction zone, wherein certain loops of the oblique fibers protrude to the outside of the outer surface of a wing of at least one L-shaped fiber element.
