SHANGHAI, Oct. 17, 2022 /PRNewswire/ -- China Petroleum
Sinopec's production line has adopted the PAN (polyacrylonitrile)-based carbon fiber precursor and large strip technologies developed by Sinopec. The project is running in two phases and is expected to be in full production in 2024, projecting an annual production capacity of 24,000 tons of protofilament and 12,000 tons of high-drag carbon fiber.
High-drag carbon fiber refers to a fabric that contains 48,000 or more filaments. This high performance material is known as the "king of new materials" and the "black gold". The product developed and manufactured by Sinopec Shanghai is a new type of high-strength carbon fiber with a carbon content of more than 95%. It has excellent mechanical properties and a specific weight less than a quarter of that of steel, but a resistance between seven and nine times greater. It is also corrosion resistant.
As this material can be widely used in the production of parts and components, it is expected to be used in an increasing number of industrial infrastructure projects in China, including those related to wind power, solar power, high-speed rail and aviation.
"Sinopec has adapted a special production line for high-drag carbon fiber, including production equipment and techniques, which has enabled us to design oxidation furnaces and carbide furnaces that revolutionize not only the main field control technology temperature, but also have a revolutionary energy-saving design, marking an important 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 carbon fiber-related patents and 46 carbon fiber composite material patents, the largest number in China and the third in the world, and by increasing investment and industrial readiness, Sinopec is committed to being a major contributor to the development of China's carbon fiber industry.
