Patent ID: 8153539

Claim:
A reinforcing fiber texture for a composite material part, the texture being formed at least in part by multi-layer three-dimensional weaving with a multi-satin weave, the texture comprising: at least a first, a second, and a third adjacent layers of weft yarns with the weft yarns of the first, second, and third layers being disposed in columns each comprising a weft yarn from each of said layers; a first set of warp yarns each warp yarn extending between the first layer of weft yarns and the second layer of wefts yarns and being deflected in alternation in one direction and in an opposite direction for taking hold in alternation of one weft yarn out of a given number of weft yarns in the first layer of weft yarns and of one weft yarn out of said number of weft yarns in the second layer of weft yarns adjacent to the first layer; and a second set of warp yarns each warp yarn extending between the second layer of weft yarns and the third layer of wefts yarns and being deflected in alternation in one direction and in an opposite direction for taking hold in alternation of one weft yarn out of said given number of weft yarns in the second layer of weft yarns and of one weft yarn out of said given number of weft yarns in the third layer of weft yarns adjacent to the second layer; both sets of warp yarns following paths that are offset relative to each other in the warp direction such that in a given weft plane, the yarns of the second weft yarn layer taken by a warp yarn of the first set and by a warp yarn of the second set are different, the weft yarns of the first layer of weft yarns taken by a warp yarn of the first set and the weft yarns of the second layer of weft yarns taken by a warp yarn of the second set belong to different columns of weft yarns and the weft yarns of the second layer of weft yarns taken by a warp yarn of the first set and the weft yarns of the third layer of weft yarns taken by a warp yarn of the second set belong to different columns of weft yarns; and said given number being an integer not less than 3.
