[0004] Technical scheme: in order to realize the above-mentioned purpose, a three axial carbon fiber weaving structure of the utility model, including carbon fiber fabric, carbon fiber fabric at least includes one fabric layer, and single fabric layer is woven by three axial a plurality of first yarn bundle, a plurality of second yarn bundle and a plurality of third yarn bundle;On single fabric layer, two first yarn bundles are in close contact with each other, two second yarn bundles are in close contact with each other, and one third yarn bundle or two or more third yarn bundles in close contact form a group, and the distance between two adjacent groups of third yarn bundles is separated, so that yarn bundle missing strip is formed between two adjacent groups of third yarn bundles.

[0005] Further, the carbon fiber fabric at least includes two fabric layers, and the yarn bundle missing strips on the two adjacent fabric layers are staggered.

[0006] Further, the fabric layer is densely packed by a plurality of block units, and each block unit is divided into a first parallelogram block, a second parallelogram block, a first rhombus block and a second rhombus block; the long side of the first parallelogram block and the second parallelogram block is two unit lengths, and the short side of the first parallelogram block, the short side of the second parallelogram block, the side length of the first rhombus block and the side length of the second rhombus block are all one unit length; the first rhombus block and the second rhombus block are arranged side by side on the long side of the first parallelogram block, and the first rhombus block and the second rhombus block have one side connected with the long side of the first parallelogram block; the second parallelogram block is arranged on the short side of the first parallelogram block, and the long side of the second parallelogram block is connected with the short side of the first parallelogram block, and the short side of the second parallelogram block is connected with one side of the second rhombus block; in the first parallelogram block, the first bundle is in the middle, the second bundle is below, and the third bundle is above; in the second parallelogram block, the first bundle is below, the second bundle is above, and the third bundle is in the middle; in the first rhombus block, the first bundle is above, and the second bundle is below; in the second rhombus block, the first bundle is above, and the second bundle is below; thus, on the fabric layer, any two adjacent third bundles are spaced apart to form a bundle missing strip between the two adjacent third bundles.

[0008] Beneficial effects: the three-axial carbon fiber weaving structure has a bundle missing strip on a single fabric layer, and the weight of the single fabric layer is reduced due to the existence of the bundle missing strip; when the carbon fiber woven fabric is composed of a plurality of fabric layers, the bundle missing strips on the adjacent fabric layers are staggered, the overall weight of the carbon fiber woven fabric is reduced, and the carbon fiber woven fabric still has good structural strength. BRIEF DESCRIPTION OF DRAWINGS

[0009] ATTACHED Fig. 1 It is a schematic view of a single fabric layer;

[0010] ATTACHED Fig. 2 It is a schematic view of a single block unit. DETAILED DESCRIPTION

[0011] The utility model will be described further in connection with the drawings.

[0012] As attached Figs. 1-2The aforementioned triaxial carbon fiber braided structure includes a carbon fiber braided fabric, which comprises at least one fabric layer. Each fabric layer is woven from a plurality of first yarn bundles 1, a plurality of second yarn bundles 2, and a plurality of third yarn bundles 3 in a triaxial manner. On a single fabric layer, adjacent first yarn bundles 1 are close together, adjacent second yarn bundles 2 are close together, and one or more third yarn bundles 3, or two or more close together, form a group. The spacing between adjacent groups of third yarn bundles 3 is staggered, forming yarn bundle gaps 9 between adjacent groups of third yarn bundles 3. Due to the presence of the yarn bundle gaps 9, the weight of a single fabric layer is reduced.

[0013] Furthermore, the carbon fiber woven fabric includes at least two fabric layers, with the yarn bundle missing strips 9 on adjacent fabric layers staggered from each other, which can reduce the overall weight of the carbon fiber woven fabric while maintaining good structural strength.

[0014] Thus, by a method similar to "spinning", yarn bundle missing strips 9 are formed on the fabric layer, reducing the amount of the third yarn bundle 3 used, thereby reducing the weight of the fabric layer.

[0015] The fabric layer is woven from a first yarn bundle 1, a second yarn bundle 2 at a 60-degree angle to the first yarn bundle 1, and a third yarn bundle 3 at a negative 60-degree angle to the first yarn bundle 1. The first yarn bundle 1, the second yarn bundle 2, and the third yarn bundle 3 are all widened carbon fiber yarn bundles, and the widths of the first yarn bundle 1, the second yarn bundle 2, and the third yarn bundle 3 are consistent.

[0016] As attached Fig. 1 As shown, the fabric layer is composed of several block-shaped units 4 closely laid together. Each block-shaped unit 4 can be divided into a first parallelogram block 5, a second parallelogram block 6, a first rhombus block 7, and a second rhombus block 8. The long side of both the first parallelogram block 5 and the second parallelogram block 6 is two unit lengths, while the short side of the first parallelogram block 5, the short side of the second parallelogram block 6, the side length of the first rhombus block 7, and the side length of the second rhombus block 8 are all one unit length.

[0017] As attached Fig. 2 As shown, the first rhombus block 7 and the second rhombus block 8 are arranged side by side on one long side of the first parallelogram block 5, and the first rhombus block 7 and the second rhombus block 8 are located below the first parallelogram block 5. The first rhombus block 7 and the second rhombus block 8 are connected by one side, and each of the first rhombus block 7 and the second rhombus block 8 has one side connected to the long side of the first parallelogram block 5.

[0018] The second parallelogram block 6 is placed on the short side of the first parallelogram block 5, and one long side of the second parallelogram block 6 is connected to one short side of the first parallelogram block 5. One short side of the second parallelogram block 6 is connected to one side of the second rhombus block 8, so that the first parallelogram block 5, the second parallelogram block 6 and the second rhombus block 8 share a common vertex.

[0019] Furthermore, in the first parallelogram block 5, the first yarn bundle 1 is located in the middle layer, the second yarn bundle 2 is located in the lower layer, and the third yarn bundle 3 is located in the upper layer. In the second parallelogram block 6, the first yarn bundle 1 is located in the lower layer, the second yarn bundle 2 is located in the upper layer, and the third yarn bundle 3 is located in the middle layer. In the first rhombus block 7, the first yarn bundle 1 is located in the upper layer, and the second yarn bundle 2 is located in the lower layer. In the second rhombus block 8, the first yarn bundle 1 is located in the upper layer, and the second yarn bundle 2 is located in the lower layer.

[0020] As attached Fig. 1 As shown, in the formed fabric layer, a gap of one third yarn bundle 3 width is left between two adjacent third yarn bundles 3, that is, any two adjacent third yarn bundles 3 are separated by the width of one third yarn bundle 3. Thus, on the fabric layer, any two adjacent third yarn bundles 3 are spaced apart, forming a yarn bundle gap strip 9 between the two adjacent third yarn bundles 3. In the block unit 4, this means that there are only two layers of yarn bundles on the first rhombus block 7 and the second rhombus block 8. Therefore, on the entire fabric layer, the ratio of the first yarn bundle 1, the second yarn bundle 2, and the third yarn bundle 3 is 2:2:1, reducing the amount of third yarn bundle 3 on the fabric layer, thereby reducing the overall weight of the fabric layer. Thus, when the carbon fiber woven fabric is composed of multiple fabric layers, the overall weight of the carbon fiber woven fabric can be reduced without reducing the number of fabric layers.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
