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.
