a carbon fiber tube

Abstract

The invention discloses a carbon fiber tube. The carbon fiber tube comprises a carbon fiber module layer, a basalt fiber module layer and an eighth fiber cloth layer which are encapsulated layer by layer from the interior to the exterior, wherein the basalt fiber module layer comprises at least two basalt fiber cloth layers, and carbon fiber tows of the eighth fiber cloth layer are arranged in a staggered mode to form staggered net meshes. Through the structure arrangement, the rate of finished products of the carbon fiber tube is improved, the strength of the carbon fiber tube is improved, and appearance lines of the carbon fiber tube are also clearer and more beautiful.

Description

technical field [0001] The invention relates to the application field of carbon fiber materials, in particular to a carbon fiber tube. Background technique [0002] refer to figure 1 , the existing carbon fiber tube generally includes eight layers, from the inside to the outside are the first carbon fiber cloth layer 101 with carbon fiber tow at 0 degrees, the second carbon fiber cloth layer 102 with 45 degrees, and the third carbon fiber cloth with 135 degrees. Cloth layer 103, the fourth carbon fiber cloth layer 104 that is 90 degrees, the fifth carbon fiber cloth layer 105 that is 0 degrees, the sixth carbon fiber cloth layer 106 that is 90 degrees, the seventh carbon fiber cloth layer 107 that is 45 degrees, and the staggered The eighth carbon fiber cloth layer 108 is provided. Since the eighth carbon fiber cloth layer 108 forms a mesh 1081 through the interlaced carbon fiber tows, the seventh carbon fiber cloth layer 107 is exposed through the mesh 1081, and the seven...

Problems solved by technology

In this process, because the carbon fiber cloth is in a soft state when it is not cured, it is easy to cause the bonding between the carbon fiber cloth layers to be loose during rolling, so that local protrusions are formed on the carbon fiber cloth; at this time, the carbon fiber cloth is coated with a film Wrapping, it is easy to form creases on the seventh carbon fiber cloth layer and the eighth carbon fiber cloth layer, which affects the performance and appearance of the carbon fiber tube

[0004] At the same time, due to the relatively hard material of the carbon fiber material, it is difficult for the seventh carbon fiber cloth layer to sink into the mesh holes of the eighth carbon fiber cloth layer even under the action of the covering film. On the one hand, the seventh carbon fiber cloth layer and the eighth carbon fiber cloth layer The degree of bonding between cloth layers is low, which affects the strength of carbon fiber tubes; on the other hand, refer to figure 2 , so that there is a large height difference between the seventh carbon fiber cloth layer and the eighth carbon fiber cloth layer, so that the creases of the seventh carbon fiber cloth layer cannot be eliminated during the grinding process; if the creases of the seventh carbon fiber cloth layer are forcibly eliminated If there are no traces, it will cause a large number of carbon fiber tows in the eighth carbon fiber cloth layer to be worn off, destroying the structure of the carbon fiber tube, and causing the carbon fiber tube to be scrapped.

Moreover, since the seventh carbon fiber cloth layer and the eighth carbon fiber cloth layer are the same type of material, their glossiness and color are the same, resulting in blurred appearance lines of carbon fiber tubes, affecting the appearance lines of carbon fiber tubes.
