Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, specifically to a high-strength carbon fiber pipe. Background Technology

[0002] Carbon fiber tubes are industrial tubular profiles manufactured using carbon fiber composite materials through a pultrusion molding process. They possess characteristics such as lightweight, high strength, and corrosion resistance. This product is made from styrene-based polyester resin through heat curing, and the production process supports customization of different cross-sectional shapes, such as round and square tubes.

[0003] Its tensile strength can reach 6-12 times that of ordinary steel, while its density is only 20%-25% of that of steel. It is widely used in high-end equipment fields such as aerospace and shipbuilding. In the civilian field, it is mainly used in the manufacture of mechanical equipment parts such as aircraft frames for model airplanes, kite support rods, and lamp brackets, as well as in sports equipment and medical devices.

[0004] The strength of existing carbon fiber tubes relies solely on the materials used in their fabrication, making it difficult to further enhance their strength. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a high-strength carbon fiber tube, solving the technical problem that the strength of carbon fiber tubes in the prior art depends solely on the material itself.

[0006] To achieve the above objectives, the following solution is provided: a high-strength carbon fiber tube, comprising a carbon fiber tube body, a stress-relief structure, and a reinforcing module, wherein the stress-relief structure is provided on the outer side wall surface of the carbon fiber tube body, and the reinforcing module is provided on the inner side wall of the carbon fiber tube body. The carbon fiber tube body comprises several layers of carbon fiber fleece, each carbon fiber fleece having a tubular structure and being nested layer by layer, with the carbon fiber fleece layers bonded together by adhesive. The stress-relieving structure is a stress-relieving mesh pattern, which is set on the surface of the carbon fiber tube body. The reinforcing module includes carbon fiber ribs and a resin bonding layer. The resin bonding layer is disposed on the inner wall of the carbon fiber tube body. A number of carbon fiber ribs are uniformly embedded in the resin bonding layer. The carbon fiber ribs are attached to the inner wall of the carbon fiber tube body and are arranged along the axial direction of the carbon fiber tube body.

[0007] Furthermore, the stress-relieving mesh pattern is concave.

[0008] Furthermore, both the adhesive and the resin bonding layer are styrene-based polyester resin.

[0009] Furthermore, the stress-relieving mesh includes several spiral patterns with opposite directions of rotation, and the spiral patterns are arranged on the surface of the carbon fiber tube body.

[0010] Furthermore, the weave patterns of each of the aforementioned carbon fiber fabrics are arranged in an interlaced pattern.

[0011] The working principle and advantages of this utility model are as follows: This high-strength carbon fiber tube forms a stress-relieving mesh by setting several concave spiral patterns with opposite directions on the surface of the carbon fiber tube body, which can reduce the internal stress when the carbon fiber tube is bent and improve the bending strength of the carbon fiber tube. At the same time, the reinforcing module at the inner side wall of the carbon fiber tube body can effectively enhance the strength of the carbon fiber tube body, thus meeting the various usage needs of users.

[0012] Figure 1 This is a perspective view of the present invention; Figure 2 This is a structural diagram of the carbon fiber tube body of this utility model.

[0013] The reference numerals in the accompanying drawings include: 1. Carbon fiber tube body, 2. Stress relief mesh, 3. Carbon fiber reinforcement, 4. Resin bonding layer, 5. Carbon fiber fleece. Detailed Implementation

[0014] The following detailed explanation illustrates the specific implementation methods: like Figures 1 to 2 As shown: A high-strength carbon fiber tube includes a carbon fiber tube body 1, a stress-relieving structure, and a reinforcing module. The stress-relieving structure is provided on the outer wall surface of the carbon fiber tube body 1. The stress-relieving structure is used to reduce the internal stress when the carbon fiber tube body 1 is bent, thereby enhancing the strength of the carbon fiber tube body 1. The reinforcing module is provided on the inner wall of the carbon fiber tube body 1. The reinforcing module can enhance the strength of the carbon fiber tube body 1. The carbon fiber tube body 1 includes several layers of carbon fiber fleece 5. Each carbon fiber fleece has a tubular structure and is layered sequentially. The carbon fiber fleece 5 is bonded together with adhesive to form the carbon fiber tube body 1. The weave patterns and orientations of adjacent carbon fiber fleece 5 are staggered, thereby enhancing the strength of the carbon fiber tube body 1.

[0015] The stress relief structure is a stress relief mesh 2, which is set on the surface of the carbon fiber tube body 1. The stress relief mesh 2 is composed of several spirals with opposite directions of rotation, and the spirals are concave. This allows the stress relief mesh 2 to reduce the internal stress of the carbon fiber tube body 1 when it is bent. The reinforcing module includes carbon fiber ribs 3 and a resin bonding layer 4. The resin bonding layer 4 is disposed on the inner wall of the carbon fiber tube body 1. Several carbon fiber ribs 3 are uniformly embedded in the resin bonding layer 4. The resin adhesive structure layer is used to tightly attach and wrap the carbon fiber ribs 3 to the inner wall of the carbon fiber tube body 1. The carbon fiber ribs 3 are arranged along the axial direction of the carbon fiber tube body 1 to enhance the strength of the carbon fiber tube.

[0016] Both the adhesive and resin bonding layer 4 are made of styrene-based polyester resin.

[0017] The specific implementation process is as follows: This high-strength carbon fiber tube is made by sequentially winding and layering multiple layers of carbon fiber fleece 5 and then heating and curing it with pre-impregnated styrene-based polyester resin. The weave patterns of adjacent layers of carbon fiber fleece 5 are staggered to avoid overlapping, thereby improving the strength of the carbon fiber tube body 1. Meanwhile, several spiral grooves with similar rotation directions are opened on the surface of the carbon fiber tube body 1 to form stress relief mesh 2, so that the stress relief mesh 2 can reduce the internal stress of the carbon fiber tube body 1 during the bending process. By setting several carbon fiber reinforcing bars 3 along their axial direction on the inner side of the carbon fiber tube body 1, the resin bonding layer 4 fixes the carbon fiber reinforcing bars 3 to the inner wall of the carbon fiber tube body 1, thereby enhancing the strength of the carbon fiber tube body 1.

[0018] This high-strength carbon fiber tube forms a stress-relieving mesh pattern 2 by setting several concave spiral patterns with opposite directions on the surface of the carbon fiber tube body 1. This reduces the internal stress of the carbon fiber tube when bending and improves the bending strength of the carbon fiber tube. At the same time, the reinforcing module at the inner side wall of the carbon fiber tube body 1 can effectively enhance the strength of the carbon fiber tube body 1, thus meeting various user needs.
