Patent number: 9926651Abstract: An add-on weaving method, a device based on this method, 3D fabric items producible by this method and device, and composite materials reinforced with such 3D fabric items. The 3D fabric items are produced directly by the add-on weaving process using Complementary Fabric, warp yarns and weft yarns. The interacting woven fabric produced by interlacing the warp and weft yarns is simultaneously integrated with the Complementary Fabric used. The Complementary Fabric and interacting woven fabric integrate in mutual through-thickness directions at their intersecting planes and create directly 3D fabric items which are useful for manufacturing delamination resistant and high-performance composite materials.Type: GrantFiled: September 4, 2013Date of Patent: March 27, 2018Assignee: BITEAM ABInventor: Nandan Khokar

Patent number: 6889720Abstract: A method and device involve simultaneously inserting weft/binding yarns and beating them up, in textile manufacturing processes like 3D-weaving and uniaxial noobing. A yarn carrier is equipped with a beating-up reed dent. In the carrier, which includes a cartridge-like yarn supplying device, the yarn is arranged around two axes of rotation and it is enclosed in a case. It is particularly suitable for 3D textile-forming processes like 3D-weaving and uniaxial noobing because of its relatively low-height but high-width and hence the possibility of carrying relatively large amount of yarn. The yarn is contained on a flanged belt that can be driven either from within or from the outside. Such a cartridge-like yarn supplier is equipped with tips that are offset or displaced oppositely about the central axis. Such a displaced arrangement of the tips directs the carriers to lay yarn in two different paths, relative to a layer of warp/axial yarns, while traversing back and forth in the same linear path.Type: GrantFiled: March 6, 2001Date of Patent: May 10, 2005Assignee: Biteam ABInventor: Nandan Khokar

Patent number: 6431222Abstract: 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: GrantFiled: November 3, 2000Date of Patent: August 13, 2002Assignee: Biteam ABInventor: Nandan Khokar

Patent number: 6338367Abstract: 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.Type: GrantFiled: September 3, 1999Date of Patent: January 15, 2002Assignee: Biteam ABInventor: Nandan Khokar

Patent number: 6186185Abstract: 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.Type: GrantFiled: September 2, 1999Date of Patent: February 13, 2001Assignee: Biteam ABInventor: Nandan Khokar
