Description

Composite woven fabric

This creation relates to a fabric, especially a composite woven fabric.

Composite woven fabrics generally woven from carbon fiber, glass fiber, aramid fiber or other high-rigidity fibers include a single layer of plain woven or diagonal woven fabric, a single unidirectional woven fabric or a multi-layer woven fabric. The woven fabric is typically used in the outer casing of a portable electronic product to provide adequate strength protection.

Referring to FIG. 5, the plain woven fabric 50 is formed by interlacing the plurality of warp fibers 51 and the plurality of weft fibers 52 at 0 degrees/90 degrees, respectively. The flat woven fabric 50 is relatively low in manufacturing cost, but The flat woven fabric 50 of the layer has low structural strength, and needs to be stacked and bonded to each other to achieve a large strength, but the warp phenomenon is easily generated after the stacking is combined, and the flat woven fabric 50 is relatively tight in structure and therefore less elastic, and is stressed. When stress concentration occurs, the structure at the force is easily damaged.

Referring to FIG. 6 , the unidirectional woven fabric 60 is formed by arranging a plurality of strands of fibers 61 in a single direction. Since the structure is relatively loose, it needs to be fixed by the binding wire 62 or immersed in a resin bath after knitting. A two- to eight-layer unidirectional woven fabric 60 is stacked on each other to achieve sufficient strength, however, warping is also likely to occur after stacking.

Referring to FIG. 7 , the multi-directional woven fabric 70 is mostly arranged by stacking a plurality of first fibers 71 and a plurality of second fibers 72 at a negative 45 degrees/45 degrees or at other angles. The multi-layer structure in which the binding wires 73 are fixed can solve the warpage problem in a plurality of weaving directions, but the manufacturing cost is high.

Since portable electronic products mostly appeal to functions such as low cost, thin thickness, and sufficient strength, although the manufacturing cost of the plain woven fabric 50 and the unidirectional woven fabric 60 is low, and can be combined by stacking to generate a large strength, the stacking is performed. After that, it is easy to produce warpage and the thickness is thick, which is difficult to achieve the requirement of regulating the thickness of the product, and the stress on the plain woven fabric 50 is not easily dispersed, and the structure is more susceptible to damage, and the multi-directional woven fabric 70 can be more The problem of warpage is solved to the weaving, but the manufacturing cost is high, so the woven fabric is not easy to achieve the functional appeal of the portable electronic product.

In order to solve the problem that the existing woven fabric is not easy to be used for portable electronic products, the main purpose of the present invention is to provide a composite woven fabric which can solve the current technical problems.

The composite woven fabric of the present invention solves the prior art problem, comprising: a first woven fabric; and an X woven fabric coupled to one side of the first woven fabric, the X woven fabric comprising a plurality of a direction zone, a plurality of second direction zones, a plurality of zonal fibers, and a plurality of warp fibers, wherein each of the first direction zones and each of the second direction zones are staggered, and each of the latitudinal fibers has a weft direction Arranged adjacent to each other, the warp fibers are arranged adjacent to each other in the warp direction, and the warp fibers are stacked Above the plurality of zonal fibers, stacked under the plurality of zonal fibers and the latitudinal fibers overlap each other, and the adjacent warp fibers are sequentially arranged in the direction of displacement of at least one zonal fiber. And the direction of the fine fiber displacement in each of the first direction regions is opposite to the direction of the displacement of the weft fibers in each of the second direction regions, and the X-woven cloth has an X-shaped radial braided form.

The composite woven fabric further includes a second woven fabric bonded to the X woven fabric different from the other side of the first woven fabric.

The composite woven fabric, wherein each of the warp fibers is superposed on the two latitudinal fibers, stacked under the two latitudinal fibers, and the latitudinal fibers overlap each other, and the respective strands are adjacent to each other. The warp fibers are sequentially aligned in the direction of a zonal fiber.

With the above technical means, the enhancements that can be obtained by the novel are:

1. The present invention is coupled to the X-woven fabric with the first woven fabric as a base, and the intersection of each of the first direction regions and the second direction regions of the X-woven fabric can form a high-strength weaving center, each of which The warp fiber and each of the weft fibers are X-shaped radiating braids around the center point of the weaving, so that although the X-woven fabric is woven in a close manner of warp and weft, it is radiated from the center of the weaving. The four weaving directions can improve the elasticity of the X woven fabric, so that the stress on the X woven fabric can be dispersed, and the structure is not easily damaged; in addition, since the X woven fabric forms four weaving directions, it is less prone to warp. The phenomenon of the curve, and the X woven fabric can achieve the same strength as the conventional flat woven fabric or the unidirectional woven fabric stacked in multiple layers, thereby effectively reducing the overall The thickness of the body; furthermore, the X-woven fabric only needs to be woven by the braiding spring to control the warp fibers of the respective strands, so the manufacturing cost is low, thereby the creation of the functional appeal of the portable electronic product.

2. The present invention incorporates the second woven fabric on the other side of the X woven fabric, or a plurality of layers of X woven fabric, depending on the strength requirements of the product.
