The application scope of chopped carbon fiber (SCF) continues to expand, and my country’s industry concentration needs to be improved

Chopped carbon fiber (SCF) refers to a material made from carbon fiber filaments chopped by a fiber cutting machine. Chopped carbon fiber has the advantages of simple preparation process, excellent processing performance, good temperature resistance, good dry fluidity, lightweight, and strong wave absorption ability. It is widely used in aerospace, automobile manufacturing, construction engineering, sports equipment and other fields.

Forming is a key link in the production of chopped carbon fiber. Its forming processes include gravity sedimentation forming method, vacuum forming method, pressure drainage forming method, solution impregnation method, etc. Vacuum forming method and pressurized liquid drainage forming method are widely used in the production process of chopped carbon fiber. The above two processes have the advantages of low operating cost, simple operation process and fast settling speed, and are suitable for continuous production. At present, Chinese companies have the ability to independently produce vacuum forming equipment, and vacuum forming is the mainstream forming process of chopped carbon fiber in my country.

According to the “2023-2028 China Chopped Carbon Fiber (SCF) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that chopped carbon fiber is widely used in aerospace, automobile manufacturing, construction engineering, sports equipment and other fields. In the field of aerospace, chopped carbon fiber has the advantages of lightweight and high temperature resistance, and can be used to manufacture aircraft tails, fuselages and other structural parts; in the field of automobile manufacturing, chopped carbon fiber can be used to manufacture automobile hoods, chassis and automobile bodies. ; In the field of construction engineering, adding chopped carbon fiber to concrete can effectively improve the stability of the building structure.

In recent years, with the continuous deepening of research, the application scope of chopped carbon fiber has been further expanded. Adding chopped carbon fiber to ultra-high molecular weight polyethylene (UHMWP) can effectively improve its friction and mechanical properties. The product can be used to make body armor and safety protection products. In 2022, the Ministry of Industry and Information Technology and the National Development and Reform Commission jointly issued the “Guiding Opinions on the High-Quality Development of the Chemical Fiber Industry”. The document clearly stated that the production and application levels of carbon fiber should be improved. Against this background, the development speed of my country’s chopped carbon fiber industry will accelerate.

There are many chopped carbon fiber manufacturers in my country, but the market is dominated by small and medium-sized enterprises, and the industry concentration is low. Chuangyu Carbon Fiber, Xingke Carbon Fiber, Xiangsheng Carbon Fiber, and Jihu Carbon Fiber are the main manufacturers of chopped carbon fiber in my country. At present, my country’s chopped carbon fiber market lacks leading companies and the market share of high-end products is low. This is the main challenge facing the development of the industry.

Industry analysts said that chopped carbon fiber, as a carbon fiber segmented product, has low production costs and excellent overall performance, and has broad applications in many fields. Application prospects. In the future, as local companies continue to increase their investment in research and development, the application scope of chopped carbon fiber will be further expanded. In terms of market competition, the concentration of my country’s chopped carbon fiber industry is low. It is expected that companies with high-performance chopped carbon fiber production capabilities will occupy a larger space in the market in the future.
