According to the latest news from Sinopec Corp., Shanghai Petrochemical, a subsidiary of Shanghai Petrochemical, has successfully developed a complete set of 48K large tow carbon fiber polymerization, spinning, and oxidation carbonization process technology. The carbon fiber produced has excellent surface structure and interface performance, and Reduce costs. Our country ’s long-standing history in this field has come to an end.
According to Huang Xiangyu, the chief of the project "Development of Polyacrylonitrile (PAN) -based Large Tow Raw Silk and Carbon Fiber Technology and Process Package" and Chief Engineer of Acrylic Department of Shanghai Petrochemical, in the industry, the number of carbon fibers per bundle is less than 24,000 (24K) It is a small tow; more than 48000 (48K) is called a large tow. Previously, the domestic large-tow carbon fiber business volume was several thousand tons per year, all of which depended on imports. The relevant core technologies were mastered by a few developed countries such as Japan and the United States, and the technical barriers were strict.
