Fibrous structure for a part made of a composite material and having a complex shape

摘要

A reinforcing fiber structure woven as a single piece for fabricating a composite material part and including: first and second fiber substructures, each fiber substructure including at least one independent portion obtained by multilayer weaving between a plurality of layers of warp yarns and a plurality of layers of weft yarns that are independent from the other substructure; and an assembly portion between the least first and second fiber substructures in which a plurality of adjacent layers of warp yarns of the first fiber substructure are interlinked by at least some of the warp yarns of the second fiber substructure.

1. A fiber reinforcing structure woven as a single piece for fabricating a composite material part, comprising:
first and second fiber substructures, each fiber substructure comprising at least one independent portion obtained by multilayer weaving between a plurality of layers of warp yarns and a plurality of layers of weft yarns that are independent from the other substructure; and an assembly portion between the at least first and second fiber substructures in which at least a plurality of layers of adjacent warp yarns or at least a plurality of layers of adjacent weft yarns of the first fiber substructure are interlinked by at least some of the warp yarns or at least some of the weft yarns of the second fiber substructure; and wherein, in the assembly portion, at least a plurality of layers of adjacent warp yarns of the first fiber substructure are interlinked by at least some of the warp yarns of the second fiber substructure.
