In June 2021, Sinopec's Shanghai Petrochemical registered Shanghai Jinshan Petrochemical Carbon Fiber Co., Ltd., a wholly-owned subsidiary of Sinopec. The new company focuses on breakthroughs and industrialization of carbon fiber technology. It not only participates in the research and development and production of new carbon fiber materials and downstream composite materials, but also involves the operation and after-sales service of the carbon fiber product market. This achievement will help reduce China's dependence on imported large-tow carbon fiber and promote high-quality development of domestic carbon fiber industry. Sinopec Produces China's First Batch of Large Tow Carbon Fiber SHANGHAI, Oct. 14, 2022 – China Petroleum & Chemical Corporation (HKG: 0386, "Sinopec") has successfully produced China's first batch of large tow carbon fiber at the company's production base in Shanghai, making the company the first in the country and fourth in the world to possess large tow carbon fiber technology. Sinopec's production line has adopted its self-developed PAN (polyacrylonitrile) base large tow precursor and carbon fiber technologies. The project is being implemented in two phases and expects to be in full production in 2024, projecting an annual production capacity of 24,000 tons of protofilament and 12,000 tons of large tow carbon fiber. Large tow carbon fiber refers to roving that contains 48,000 filaments or more. The high-performance material is often referred to as the "king of new material" and "black gold." The product developed and manufactured by Sinopec Shanghai is a new type of high-strength carbon fiber with a carbon content of over 95 percent. It has outstanding excellent mechanical properties and a specific gravity that's less than one fourth of the steel, yet a strength that's seven to nine times stronger. It is also corrosion resistant. As the material can be widely used in producing parts and components, it is expected to be used for an increasing amount of industrial infrastructure projects in China, including ones related to wind power, solar power, high-speed rail, and aviation. "Sinopec has customized a special production line for large tow carbon fiber, including production equipment and techniques, which has enabled us to design oxidizing furnaces and carbide furnaces that revolutionizes not only the core technology of temperature field control, but also has a revolutionary energy-saving design, marking a major milestone in the development of China's carbon fiber industry," said Huang Xiangyu, carbon fiber expert and deputy general manager of Sinopec Shanghai. Sinopec now owns 251 patents related to carbon fiber and 46 patents for carbon fiber composite materials, the largest number in China and third in the world, and through scaled up investment and industrial layout, Sinopec is committed to being a major contributor to the development of China's carbon fiber industry. Oct. 24, 2024 – Shanghai Petrochemical carbon fibre composite experimental base opened. This initiative reflects the requirements and efforts of Chinese conglomerate Sinopec (parent company of Shanghai Petrochemical) to build a world-class carbon fibre industrial base. This will effectively achieve a seamless transition from small trials to pilot trials, and then to industrialised technology development, forming a series of solutions from composite material development to application, and further giving full play to industry, academia and research. At present, a number of experimental production lines have been built or are under construction, including a thermoplastic panel line, a thermoplastic prepreg line, a thermoset prepreg line, a panel pultrusion line, a threaded bar pultrusion line, a fabric pultrusion line and a high-performance resin line. The resin line has pilot and mass production capabilities for composite materials with thermosetting and thermoplastic properties, and diversified preparation processes. In the future, Shanghai Petrochemical says it will continue to improve its technical level and production capacity, actively moving towards the goal of “strengthening and optimising the new materials industry with carbon fibre as the core“. |
