At present, the world's carbon fiber production reaches 40,000 tons/year. The world is mainly Japan Toray, Toho rayon and Mitsubishi Rayon and the US HEXCEL, ZOLTEL, ALDILA, and the German SGL SGL Group, Korea. Taiguang Industry, Formosa Plastics Group of Taiwan Province of China, and other small units have mastered the core technology of carbon fiber production and have large-scale production. China's research on carbon fiber began in the 1960s, and in the 1980s it began to study high-strength carbon fiber. Progress has been slow over the years, but it has also achieved certain results. Since the beginning of the 21st century, Anhui Huasheng Carbon Fiber Co., Ltd. has taken the lead in introducing 500 tons/year of raw silk and 200 tons/year of PAN-based carbon fiber (only Dongli carbon fiber T300 level), which has made China's carbon fiber industry into industrialization. Subsequently, some manufacturers have joined the ranks of carbon fiber production. Since 2000, China's carbon fiber has diversified into technology, and abandoned the original nitric acid raw silk manufacturing technology. The one-step wet spinning technology with dimethyl sulfoxide as solvent has been successful. At present, a small number of domestic T300 and T700 carbon fiber products developed by independent technology have reached the level of international similar products. Carbon fiber production line With the increasing demand for carbon fiber in China in recent years, carbon fiber has been listed as a new product supported by the national chemical fiber industry, and has become a hot spot in the research and development of new materials industry in China.
