Description

Technical Field

[0001] This utility model relates to the field of carbon fiber weaving technology, and in particular to a lightweight carbon fiber triaxial fabric. Background Technology

[0002] Carbon fiber braided fabrics are textiles made from carbon fiber through textile processes. They retain the excellent properties of carbon fiber, such as high strength, lightweight, and corrosion resistance, while also possessing good flexibility and processability. Triaxial braiding refers to a fabric woven from three different angles of yarn bundles. Currently, in carbon fiber triaxial braided structures, the three yarn bundles are used in equal proportions, making it difficult to achieve lighter fabrics. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a lightweight carbon fiber triaxial fabric, which aims to reduce the weight of the fabric.

[0004] Technical Solution: To achieve the above objectives, this utility model provides a lightweight triaxial carbon fiber fabric, comprising a carbon fiber fabric layer woven from a first yarn bundle, a second yarn bundle, and a third yarn bundle. The carbon fiber fabric layer is densely covered with several block-shaped units. Each block-shaped unit is divided into a first parallelogram block, a second parallelogram block, a third parallelogram block, a fourth parallelogram block, a first rhombus block, a second rhombus block, a third rhombus block, and a fourth rhombus block. The long side of the first parallelogram block, the second parallelogram block, the third parallelogram block, and the fourth parallelogram block is two unit lengths. The short side of the first parallelogram block, the second parallelogram block, the third parallelogram block, and the fourth parallelogram block are all two unit lengths. The short side of the quadrilateral block, the side length of the first rhombus block, the side length of the second rhombus block, the side length of the third rhombus block, and the side length of the fourth rhombus block are all one unit length. The first, second, and third parallelogram blocks share a common vertex, are distributed in a triangular shape, and are arranged clockwise. The long side of the first parallelogram block connects to the short side of the second parallelogram block, the long side of the second parallelogram block connects to the short side of the third parallelogram block, and the long side of the third parallelogram block connects to the short side of the first parallelogram block. The first rhombus block is placed between the first and second parallelogram blocks, and two adjacent sides of the first rhombus block connect to the long side of the first parallelogram block and the short side of the second parallelogram block, respectively. The long side of the parallelogram block; the second and third rhombus blocks are arranged side by side between the second and third parallelogram blocks, with one side of each of the second and third rhombus blocks connected to the long side of the third parallelogram block; the fourth rhombus block and the fourth parallelogram block are arranged between the third parallelogram block and the first parallelogram block; two adjacent sides of the fourth rhombus block are connected to the long side of the first parallelogram block and the short side of the fourth parallelogram block, respectively; one long side of the fourth parallelogram block is also connected to one long side of the third parallelogram block; in the first parallelogram block, the first yarn bundle is on top, the second yarn bundle is in the middle, and the third yarn bundle is at the bottom; in the second parallelogram block, the first yarn bundle is at the bottom, and the second yarn bundle is on top. The third yarn bundle is in the middle; in the third parallelogram block, the first yarn bundle is in the middle, the second yarn bundle is below, and the third yarn bundle is above; in the fourth parallelogram block, the first yarn bundle is in the middle, the second yarn bundle is below, and the third yarn bundle is above; in the first rhombus block, the first yarn bundle is below, the second yarn bundle is above, and the third yarn bundle is in the middle; in the second rhombus block, the first yarn bundle is above, the second yarn bundle is in the middle, and the third yarn bundle is below; in the third rhombus block, the first yarn bundle is above, the second yarn bundle is in the middle, and the third yarn bundle is below; in the fourth rhombus block, the first yarn bundle is below, the second yarn bundle is above, and the third yarn bundle is in the middle; on the carbon fiber fabric layer, every three adjacent second yarn bundles form a group, and the spacing between two adjacent groups of second yarn bundles is separated, thereby forming a yarn bundle gap strip between two groups of second yarn bundles.

[0005] Furthermore, the widths of the first yarn bundle, the second yarn bundle, and the third yarn bundle are the same.

[0006] Furthermore, the second yarn bundle is at a 60-degree angle to the first yarn bundle, and the third yarn bundle is at a negative 60-degree angle to the first yarn bundle.

[0007] Furthermore, several carbon fiber fabric layers are stacked to form a carbon fiber braid; on the carbon fiber braid, the missing yarn strands on two adjacent carbon fiber fabric layers are staggered.

[0008] Beneficial effects: The present invention discloses a lightweight triaxial carbon fiber fabric. The carbon fiber fabric layer is woven from a first yarn bundle, a second yarn bundle at a 60-degree angle to the first yarn bundle, and a third yarn bundle at a negative 60-degree angle to the first yarn bundle. On the formed carbon fiber fabric layer, every three adjacent second yarn bundles form a group, and there is a gap of one second yarn bundle width between two adjacent groups, that is, a yarn bundle gap strip is formed between two groups of second yarn bundles. Thus, the ratio of the amount of the first, second, and third yarn bundles on the carbon fiber fabric layer is 4:3:4, thereby reducing the amount of second yarn bundles on the fabric and thus reducing the weight of the fabric.

The longer side of each of the four parallelogram blocks is two units long, while the shorter side of each of the four parallelogram blocks is one unit long.

[0014] As attached Figure 2 As shown, the first parallelogram block 5, the second parallelogram block 6, and the third parallelogram block 7 share a common vertex and are arranged in a triangular shape, in a clockwise direction.

The two adjacent sides of the first rhombus block 9 are respectively connected to one long side of the first parallelogram block 5 and one long side of the second parallelogram block 6.

[0016] The second rhombus block 10 and the third rhombus block 11 are arranged side by side between the second parallelogram block 6 and the third parallelogram block 7. The second rhombus block 10 and the third rhombus block 11 are connected by one side, and each of the second rhombus block 10 and the third rhombus block 11 has one side connected to one long side of the third parallelogram block 7.

[0017] The fourth rhombus block 12 and the fourth parallelogram block 8 are positioned between the third parallelogram block 7 and the first parallelogram block 5. The fourth rhombus block 12, the third parallelogram block 7, and the fourth parallelogram block 8 share a common vertex. Two adjacent sides of the fourth rhombus block 12 are connected to the long side of the first parallelogram block 5 and the short side of the fourth parallelogram block 8, respectively. One long side of the fourth parallelogram block 8 is also connected to one long side of the third parallelogram block 7.

[0018] In the first parallelogram block 5, the first yarn bundle 1 is in the upper layer, the second yarn bundle 2 is in the middle layer, and the third yarn bundle 3 is in the lower layer;

[0019] In the second parallelogram block 6, the first yarn bundle 1 is in the lower layer, the second yarn bundle 2 is in the upper layer, and the third yarn bundle 3 is in the middle layer;

[0026] Based on the above structure, as shown in the appendix Figure 1 As shown, on the formed carbon fiber fabric layer, every three adjacent second yarn bundles 2 form a group, and the spacing between two adjacent groups of second yarn bundles 2 is spaced apart, thereby forming a yarn bundle gap strip 13 between two groups of second yarn bundles 2. Thus, on the carbon fiber fabric layer, the ratio of the amount of first yarn bundle 1, second yarn bundle 2 and third yarn bundle 3 is 4:3:4, thereby reducing the amount of second yarn bundle 2 on the carbon fiber fabric layer and thus reducing the weight of the fabric.

[0027] Furthermore, several carbon fiber fabric layers are stacked to form a carbon fiber braid; on the carbon fiber braid, the yarn bundle missing strips 13 on two adjacent carbon fiber fabric layers are staggered.
