Abstract
A novel woven fabric is provided wherein preferably two unidirectional mutually offset and at least partly overlapping layers of tape-like warps interlace with tape-like wefts, at least some being fibrous tapes, that are incorporated individually in either non-overlapping manner or in a mutually offset and overlapping manner relative to other weft tapes. Such a woven fabric is without see-through gaps at the areas/sites encircled by intersecting tape-like warps and wefts, and also delamination resistant. It is particularly suitable for composite material, ballistic mitigation, and similar applications.

A woven fabric comprising warps and wefts of tapes, wherein all of the warps and wefts are fibrous tapes, wherein the warps and wefts interlace, and wherein both the warps and the wefts are arranged in at least two unidirectional and at least partly overlapping layers, wherein at least one warp and at least one weft of one layer is offset in relation to warps and wefts in the other layer so that each of the offset warp and weft overlies and covers at least one longitudinal gap between adjacent warps or wefts in the other layer, wherein all the tapes have a thickness lower than their widths, and wherein the mutually offset and partly overlapping warps and wefts of the at least two layers mutually interlace to form a delamination resistant woven fabric.
A woven fabric comprising warps and wefts of tapes, wherein all of the warps and wefts are fibrous tapes, wherein the warps and wefts interlace, and wherein the warps are arranged in at least two unidirectional and at least partly overlapping layers,
- wherein at least one warp of one layer is offset in relation to warps in the other layer so that the offset warp overlies and covers at least one longitudinal gap between adjacent warps in the other layer, wherein at least some warps in these layers are grouped in units of grouped warps comprising warps from each of said at least two layers, whereby each weft interlaces with the units of grouped warps, and wherein units of grouped warps are interlacing with individual wefts, wherein the individual wefts are incorporated in a mutually offset and overlapping arrangement relative to each other, and wherein all the tapes have a thickness lower than their widths.
