WOVEN FABRIC BASE MATERIAL AND FIBER-REINFORCED COMPOSITE MATERIAL

WIPO Patent Application WO/2013/035518

A1

A woven fabric base material comprises: multiple reinforcing fiber warp yarns, each of which comprises a fiber bundle and which are arranged in parallel with each other; and multiple reinforcing fiber weft yarns, each of which comprises a fiber bundle and which are arranged in parallel with each other and are also arranged so as to intersect the reinforcing fiber warp yarns. Multiple auxiliary weft yarns, each of which comprises a finer yarn than each of the reinforcing fiber weft yarns and which extend in the same direction as those of the reinforcing fiber weft yarns, are arranged on the opposite side of the reinforcing fiber warp yarns from the reinforcing fiber weft yarns. Multiple auxiliary warp yarns each comprising a finer yarn than each of the reinforcing fiber warp yarns extend in the same direction as those of the reinforcing fiber warp yarns, are individually arranged between adjacent two of the reinforcing fiber warp yarns, and are also arranged in such a manner that both folding-back sections that are engaged with the reinforcing fiber weft yarns and folding-back sections that are engaged with the auxiliary weft yarns exist therein.
