FIELD: textiles, paper.
SUBSTANCE: reinforcing fibrous structure (100) for a part of a composite material is integrally woven by the multi-layer weaving between the plurality of layers of weft yarns (102) and a plurality of layers of warp yarns (101) located between two adjacent surfaces of the said structure. The fibrous structure (100) comprises at least one arcuate section (120) extending along one of the surfaces of the fibrous structure (100), at that the arcuate section (120) comprises at least some of the warp yarns (101) continuous with at least two adjacent layers of warp yarns contained on one of the surfaces of the structure (100). The warp yarns of the arcuate section (120) have a length greater than that of the warp yarns of at least two underlying layers of warp yarns of the structure (100). In addition, the warp yarns of the arcuate section (120) are not interconnected with the other warp yarns of the fibrous structure (100).
EFFECT: strengthening of the structure.
