The invention relates to a fiber structure (200) for reinforcing a composite material part woven into a single part by means of multilayer weaving between a first plurality of thread layers (C1-C10) and a second plurality of thread layers (T1-T10). The fiber structure includes a portion (204) having a decreasing thickness and has a plurality of surface continuity thread setback portions (210, 211, 212) on said portion, wherein each portion has threads (Fc3; Fc8; Fc4), from a thread layer (C3; C8; C4) of the first thread layer plurality underlying the thread layer of the first thread layer plurality located on the surface of the structure, that are interrupted, and several surface discontinuity thread setback portions (220, 221), wherein each portion has threads (Fc1; Fc10), from the thread layer (C1; C10) of the first thread layer plurality located on the surface of the structure, that are interrupted. Each interrupted thread (Fc1; Fc10) is replaced, on the surface of the structure, by a thread (Fc2; Fc9) from a thread layer (C2; C9) underlying the first thread layer plurality. The threads from the layers from the second thread layer plurality (T1- T10), located on the surface of the fiber structure, are continuous over at least the entire portion (204) having a decreasing thickness. |
