To understand the history of domestic carbon fiber development, we mainly look at articles published by Li Kejian, Li Shangyuan, Zhao Jiaxiang and others.

1. In 1962, the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences established the "Development of Polyacrylonitrile-Based Carbon Fibers" led by Li Shangyuan, and carried out a large number of basic research.

2. In the early 1970s, in order to meet the national defense needs of the Chinese Academy of Sciences, the Institute of Polymer Physics and the Special Polymer Materials Laboratory set up some 803 and 804 groups, and then formed a polymer on the basis of the two groups. Laboratory of Composite Materials Physics (Nine Room, Director: Wu Renjie); focus on "continuous preparation of carbon fiber" and "reduction of carbon fiber preparation cycle" and achieved results such as "tin tetrachloride" catalysis.

3. In 1972, the Jilin Chemical Research Institute of the Ministry of Chemical Industry carried out the development of carbon fiber PAN raw silk by the nitric acid method, and obtained the raw silk by one-step method of obtaining nitric acid on the annual output of 3 tons, for the research of carbon fiber by Shanxi Burning Chemical Institute and Changchun Yinghua Institute. Shanxi Burning, so indirect pre-oxidation and carbonization research, and carried out continuous pre-oxidation and carbonization tests.

4. In the early 1970s, the Shanghai Institute of Synthetic Fibers conducted research on acrylonitrile precursors of thiocyanate. In 1975, it supplied carbon fiber to 2 tons of raw silk from the Shanghai Carbon Plant of the Ministry of Metallurgy.

5. The “7511” meeting was held in Beijing on November 13-24, 1975.

6. The three process routes of PAN-based carbon fiber precursors developed the one-step method of nitric acid from Jilin Chemical Research Institute to terminate production in 1998, and cooperated with Beijing University of Chemical Technology and Changchun University of Technology to carry out DMSO one-step production of carbon fiber precursor; Lanzhou chemical fiber plant thiocyanate The production of sodium raw silk was terminated due to suspension of production in 2005. It was developed by Shanghai Petrochemical Acrylic Fiber Division and is expanding its annual production capacity of 3,000 tons. The sulfoxide method was promoted by Shanxi Coal Chemical Institute and Beijing University of Chemical Technology. Above the original silk enterprises, the main sources of technology are mainly Jilin Petrochemical and Shanxi Coal Chemical Institute. Among them, Zhongfu Shenying and Danyang Hengshen technology mainly come from Shanghai Donghua University and foreign equipment manufacturers; dimethylacetamide method by Jilin Chemical fiber and Changchun University of Technology jointly developed, Jilin Carbon Valley Co., Ltd.

From 7, 75 to 90 years, foreign carbon fiber entered a stage of rapid development, but the country only realized that it had no products and could not scale production.

8. From 1991 to 1999, the gap between domestic carbon fiber and Japan is growing, and the development has entered a period of low tide.

9. In 2000, carbon fiber development entered a new stage. In 2007, production capacity entered a stage of rapid development; currently there are nearly 30 domestic enterprises.
