            How to improve the carbon fiber tube material?
            2019-10-18

            Carbon fiber is widely used because of its superior strength to steel and excellent weight-reducing effect. Carbon fiber tube is the main application form. Usually, carbon fiber tube will appear in some parts of the system, so how to improve the quality of the tube is particularly important. Experience gained from the carbon fiber production process for many years.


            Since it is necessary to improve the quality of carbon fiber pipe, it is necessary to understand the cause of defects in carbon fiber pipe. Generally, the surface defects of carbon fiber pipe mainly have wrinkles and streaks, and the reasons for traceability are mainly concentrated in the prepreg layup. When laminating, if sufficient tension is applied to compress the prepreg stack quickly, the prepreg of each layer will be relatively loose and the overall thickness will increase. However, if the pressurization brings about a contraction force, the carbon fiber is bent and folded. Also, some auxiliary materials are required in the prepreg layup, which also cause wrinkles when compressed.


            After talking about the reasons, the following is a brief introduction to the solution. The first important step is to combine the pre-compression with the temperature during the laying process of the carbon fiber prepreg. Generally, each layer is laid at a certain temperature. Pre-compression is carried out so that timely pre-pressure can prevent the layer of fiber slack from accumulating. The resin content and tube thickness in the carbon fiber composite can be effectively controlled. Secondly, it is very important to select a suitable mold. The choice of the mold has a great influence on the outer diameter. For the material of the core mold, a metal material with good rigidity is required to improve the density and rigidity of the carbon fiber tube. In addition, the heat shrinking process can be used to improve the surface quality and precision of carbon fiber tubes.
