FIBROUS REINFORCING STRUCTURE OF COMPLEX SATIN WEAVE FOR MAKING DETAIL FROM COMPOSITE MATERIAL Russian patent published in 2012 - IPC D03D25/00 

FIELD: textiles, paper.

SUBSTANCE: invention relates to a fiber reinforced structure for detail made of a composite material formed at least in part through a multi-layer three-dimensional weaving with a weave of complex satin weaving, comprising: at least first, second and third adjacent layers of weft threads, and weft threads of the first, second and third layers are located in columns, each of which contains a weft thread of each of the said layers, the first set of warp yarns, in which each warp thread one by one grabs one weft thread from the number n of the yarns of the first layer of weft threads and one thread of the number n of the second layer of weft threads adjacent to the first, and the second set of warp yarns, in which each warp thread one by one grabs one weft thread from the number n of yarns of the second layer of weft threads and one thread from the number n of the third layer of weft thread adjacent to the second, with both sets of warp yarns follow the similar routes, but with offset relative to one another in the direction of the warp, so that in the same planes of weaving the threads of the second layer of weft threads captured by warp thread of the first set and by warp thread of the second set are different, and n is an integer number at least equal to 3.

EFFECT: provision of sufficient communication between the layers to prevent delamination without affecting the mechanical strength in a direction parallel to the planes of the layers.
