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 in VIA. The experience summarized in the production process of new materials for many years, this article Xiaobian mainly introduces how to improve the quality of carbon fiber pipe.
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.
