  • Patent number: 6431222
    Abstract: A network-like woven 3D fabric material includes select multilayer warp yarns occurring substantially linearly, the remainder multilayer warp yarns occurring in a helical configuration and two orthogonal sets of weft. This network-like fabric construction is made possible through a dual-directional shedding operation of the weaving process. Such a fabric may additionally incorporate non-interlacing multi-directionally oriented yarns across the fabric cross section to improve the fabric's mechanical performance. The produced 3D fabric material, which may be cut into any desired shape without the risk of splitting, may be used wholly or in parts in technical applications.
    Type: Grant

  • Patent number: 6338367
    Abstract: A woven 3D fabric material comprises multilayer axial warp yarns and two orthogonal sets of weft which interlace with the rows and the columns of the warp respectively to provide integrity to the fabric which may additionally incorporate between the rows and the columns of the interlacing warp sets of non-interlacing multi-directionally orientated yarns in the fabric-length, -width, -thickness, and two diagonal directions respectively to improve the fabric's mechanical properties. The interlacing of the multilayer warp and the two orthogonal sets of weft is enabled by a dual-directional shedding means which forms sheds in the row-wise and the column wise directions of the multilayer warp. The produced woven 3D fabric material which may be cut into any desired shape without the risk of splitting up, may be wholly or in parts in technical applications.

  • Patent number: 6186185
    Abstract: A network-like woven 3D fabric material (9) comprises select multilayer warp yarns (8) occurring substantially linearly, the remainder multilayer warp yarns (7) occurring in the helical configuration and two orthogonal sets of weft (12c and 12r) and such a network-like fabric construction (9) made possible through a dual-directional shedding operation of the weaving process. Such a fabric may additionally incorporate non-interlacing multi-directionally oriented yarns (n1-n8) across the fabric cross section to improve the fabric's mechanical performance. The produced 3D fabric material, which may be cut into any desired shape without the risk of splitting, may be used wholly or in parts in technical applications.
