Abstract
The present invention is to provide methods to increase composite interlaminate strength and interface strength, and make 3D fibers products, prepregs and composites, by using trans-interface and/or trans-fiber products such as trans-plies, strands and/or yarns fastening components selected from the group comprising of hooks and loops (velcro), hooks and hooks, zipper heads, fish hook shape hooks, staples, arrow heads, forks and mushroom heads. One ply of fibers has one or multiple of the above fasteners on at least one side. Lay-up the plies with said fastening components on its one or two sides to obtain a 3D fiber products with those fastening components locked together. The plies can be separated if need re-lay-up. A thread or a yarn have the fastening components around 0-360 degree on its surface. Lay the threads together or intercross each other to get a 3D fiber products. In those 3D fiber products, two parts of the fastening components lock each other if they meet and engage. A 3D composite can be made using the 3D fiber products.
One fiber ply with the fasteners on its at least one side, is impregnated or protruded with matrix materials, a piece of the prepreg with the fasteners prepreg with the fasteners are made. Lay and press the prepreg together fastening components will lock each other if they meet and engage. In most of production processes, the matrix materials might soften and meld, and the fastening components will further interlock each other. So a 3D composite structure is made by the said 3D prepregs. Those fastening components may stay just partially or fully in matrix at matrix surface. The fastening components increase the interface strength when two matrix materials meet just by crossing interface even if they are not locked and without fiber products in matrix.

21. A fiber product comprising:
-
at least one fiber-made article selected from the group comprising of fiber plies, sheets, blocks, fabrics, blankets, cushions, meshes, nets, cloth, filaments, threads, yarns, wires, at least one of fastening components selected from the group comprising of Velcro fasteners, hooks and loops, hooks and hooks, hooks, loops, fish hook shape hooks, arrow hooks, anchor hooks, mushroom heads, ties, knots, forks, branchs, knot chains, hook chains, staples and, zipper heads, arrow heads, chain hooks, chain loops, teeth, screws, coils, and loop-shape hook fasteners said fastening components are on/in one or both sides or around of said fiber-made article at predetermined areas;
or said fastening components may act alone without said fiber-made article,wherein two or more said fiber-made articles can link or lock together by said fastening components at predetermined areas, or wherein said fastening components can link other substances at interface to improve the interface properties. - View Dependent Claims (22, 23, 24, 25, 34, 35, 36, 37, 38, 39, 40)

26. A composite made from two or more materials to obtain better physical or chemical properties comprising:
-
at least one fiber-made article selected from the group comprising of fiber plies, sheets, blocks, fabrics, blankets, cushions, meshes, nets, cloth, filaments, threads, yarns, wires, at least one kind of one or multiple fastening components selected from the group comprising of Velcro fasteners, hooks and loops, hooks and hooks, hooks, loops, fish hook shape hooks, arrow hooks, anchor hooks, mushroom heads, ties, knots, forks, branchs, knot chains, hook chains, staples and, zipper heads, arrow heads, chain hooks, chain loops, teeth, screws, coils, and loop-shape hook fasteners, at least one kind of matrix materials, said fastening components are on/in one or/and both sides or/and around of said fiber-made article at predetermined areas; wherein two or more said fiber-made articles can link or lock together by said fastening components at predetermined areas to make a stronger composite, or wherein said fastening components may act alone without said fiber-made article, so that said fastening components can link other substances at interface to improve the interface properties. - View Dependent Claims (27, 28, 29)

30. In a method for producing fiber product and composite, the method comprising:
-
at least one or multiple of fastening components selected from the group comprising of Velcro fasteners, hooks and loops, hooks and hooks, hooks, loops, fish hook shape hooks, arrow hooks, anchor hooks, mushroom heads, ties, knots, forks, branchs, knot chains, hook chains, staples and, zipper heads, arrow heads, chain hooks, chain loops, teeth, screws, coils, and loop-shape hook fasteners said fastening components can link other substances at interface to improve the interface properties, wherein the substance surfaces may have fastening components embed in/on its surfaces, which can increase the interface strength when said substance surface having fastening components meets another substance surface with or without said counterparts of fastening components, the fastening components can be transversely laid through the interface of two substance and make the interface stronger by the link of fasteners or by the locked fasteners. - View Dependent Claims (31, 32, 33)
