The development prospects of the carbon fiber prepreg industry are good, and the domestic substitution process in the domestic market is accelerating.

Carbon fiber prepreg, also known as carbon fiber prepreg, refers to a composite material made of carbon fiber yarn, epoxy resin and other materials through dry or wet processes. According to different weaving methods, carbon fiber prepregs can be divided into wet prepregs, dry prepregs, unidirectional prepregs, etc.

The main preparation methods of carbon fiber prepreg include hot melt method and solution method. The hot-melt method refers to using hot-melt impregnation to press-impregnate the resin film, release paper and carbon fiber under certain pressure and temperature conditions, and then go through processes such as cooling, drying, and cutting to produce carbon fiber prepregs. The hot melt method is suitable for large-scale production and is widely used in my country’s carbon fiber prepreg market.

Carbon fiber prepreg has the advantages of good mechanical properties, high strength, and low density, and is mainly used in the field of wind power generation. As an important field of green and environmentally friendly new energy, wind power can effectively achieve ecological protection and sustainable development of electricity. At present, my country has built wind power generation bases in most areas of North China, Northwest China, and East China, and the installed wind power capacity is increasing year by year. Carbon fiber prepreg is mainly used in the manufacturing of wind power blades. With the rapid development of the wind power industry, my country’s carbon fiber prepreg market continues to expand.

In terms of import and export, my country’s local companies mainly produce mid- to low-end carbon fiber prepregs, and high-end products are highly dependent on imports. According to statistics from the General Administration of Customs of China, my country’s carbon fiber prepreg imports from January to April 2022 reached 868.2 tons, a year-on-year increase of 48.7%; exports reached 291.7 tons, a year-on-year increase of 93.7%. In recent years, driven by technological innovation, the domestic substitution process in my country’s carbon fiber prepreg industry has accelerated. It is expected that my country’s carbon fiber prepreg imports will show a slow downward trend in the future.

According to the “2022-2027 China Carbon Fiber Prepreg Industry Market Supply and Demand Status and Development Trend Forecast Report released by the Industrial Research Center In terms of market competition, the world’s leading carbon fiber prepreg companies are concentrated in Japan and the United States, including Japan’s Toho Chemical TOHO, Japan’s Mitsubishi Rayon MITSUBISHI, the United States’ ZOLTEK, and the United States’ HEXCEL, etc. my country’s carbon fiber prepreg industry started late, but is developing rapidly. Weihai Guangwei Composite Materials, Jiangsu Hengshen, and Jiaxing Zhongbao Carbon Fiber are the main carbon fiber prepreg manufacturers in my country. Driven by leading enterprises, the output value of my country’s carbon fiber prepreg continues to grow. In 2021, the output value of my country’s carbon fiber prepreg will exceed 2 billion yuan.

Industry analysts said that as a new black material, carbon fiber prepreg’s industry development is closely related to technological maturity and market demand. contact. Carbon fiber prepregs are widely used in my country, with wind power generation blades being the largest demand end. With the rapid development of downstream industries, my country’s carbon fiber prepreg market will continue to expand, and there is huge potential for industry development.
