Novel woven materials, producible by a new weaving method, are described that comprise single or doubled warps and wefts in the form of tapes that are preferably partially stabilized type of fibrous tape. These fibres are caused to occur in a non-linear arrangement during the weaving process. The non-linear fibres can be subsequently straightened by pulling the tape longitudinally. The doubled warps and wefts comprise disconnected tapes. Such separateness of constituent tapes of doubled warp and weft tapes enables them to be slid/slipped relative to each other by pulling longitudinally and laterally without causing any alteration in the woven structure. These novel fabrics solve the problem of uneven fibre distribution and orientation arising from crumples/wrinkles due to compression and stretches due to extension, at the inner and outer sides respectively, when tape-woven fabrics are curved into shapes. Further, by using doubled warps and wefts fabrics with relatively flat/planar sections and thicker/raised wide rib sections can be also created that resemble a bit like a profiled material in its cross-section. Other fabrics like those comprising slant/oblique weft tapes, shaped warp and weft tapes, formed shape within its body are also producible.

1. A woven material comprising warps and wefts of tapes, wherein at least one of the warp and weft is a partially stabilized fibrous tape where fibers are discontinuously connected by a binding agent in such a way that only some fibers across the tape width are held while leaving some fibers free, whereby the warps and the wefts are held together via interfacing thereof in such a way that the warps and the wefts are configured to slip and slide or slide laterally and longitudinally in relation to each other. 2. The woven material of claim 1, wherein the at least one partially stabilized fibrous tape includes fibers orientating non-linearly in the tape's length direction, whereby said non-linear fibers are able to be straightened without altering a weave structure or pattern. 3. The woven material of claim 2, wherein most of the fibers in the at least one partially stabilized fibrous tape orientates non-linearly in the tape's length direction. 4. The woven material of claim 2, wherein most of the warp and weft tapes have fibers orientating non-linearly in the tape's length direction. 5. The woven material of claim 1, wherein at least one of the warp and weft tapes is a doubled tape including at least two separate tape layers being loosely arranged on top of each other in a thickness direction of the woven material. 6. The woven material of claim 1, wherein at least some of the warp and weft tapes occur in a slanted disposition with an obtuse angle therebetween. 7. The woven material of claim 6, wherein at least some of the warp and weft tapes occur in different angular dispositions, with different angles therebetween. 8. The woven material of claim 1, wherein the woven material has at least one contoured shape within a body of the woven material. 9. The woven material of claim 1, wherein at least some of the warp and weft tapes have edges selected from non-linear longitudinal edges, non-parallel edges and a combination of such edges. 10. The woven material of claim 1, wherein some of the partially stabilized fibrous tapes have different thicknesses relative to each other. 11. The woven material of claim 1, wherein at least one of the partially stabilized fibrous tapes is a doubled tape including two separate tape layers being loosely arranged on top of each other in a thickness direction of the woven material. 12. The woven material of claim 1, wherein at least some of the warp and weft tapes are of different widths. 13. The woven material of claim 1, wherein at least some of the warp and weft tapes have different thicknesses. 14. The woven material of claim 12, wherein the warp and weft tapes of different widths occur in a regular pattern in the woven material. 15. The woven material of claim 1, wherein at least one loosely arranged tape layer of a doubled warp and weft tape is slideable relative to the other without altering a weave pattern of the woven material. 16. The woven material of claim 1, wherein the woven material has a variable weight per unit area. 17. The woven material of claim 1, wherein a material of the warp and weft tapes is selected from at least one of thermoplastic, polymeric, synthetic, thermoset, metallic, organic, inorganic, impregnated fibers, natural, vegetable and animal fibers, aramid fibers, carbon fibers, boron fibers, ceramic fibers, glass fibers, optical fibers and a combination of at least some of them. 18. The woven material of claim 1, wherein the construction of the warp and weft tapes are at least one of flat, solid, profiled on one side and flat on the other, shaped at edges, perforated, embossed, corrugated, tapered, smooth, rough, transparent, opaque, translucent, colored, colorless, stabilized fibers, non-stabilized fibers, adhesive bearing and a combination of them. 19. The woven material of claim 1, wherein the woven material includes at least one of an thermoplastic and a uncured matrix to form a prepreg material. 20. The woven material of claim 1, wherein at least one loosely arranged tape layer of a doubled warp and weft tape is removable relative to the other without altering a weave pattern of the woven material.
