Carbon fiber is a high-strength, high-modulus new fiber material with a carbon content of more than 95%. It is not only an important material in the field of national defense, but also widely used in civilian applications.
On March 8th, Shanghai Petrochemical successfully produced a 48K large tow carbon fiber in the real sense in China, and it has passed through the whole process. This technology marks a breakthrough in the production and production technology of domestic carbon fiber K raw silk, which fills the domestic market. blank.
On March 12th, Shanghai Petrochemical again reported that the company successfully sold 221,98 kilograms of carbon fiber products to South Korea to achieve zero breakthrough in its export of carbon fiber products. It is reported that during the January-February period of this year, the sales volume of Shanghai Sinopec's carbon fiber products increased by 60% over the same period.
It is understood that Shanghai Petrochemical has conducted independent research and experiments on the industrialization of carbon fiber 48K tow filaments since May 2016. From January this year, the company and the Shanghai Research Institute of Petroleum and Chemical Industry conducted an oxidative carbonization test on the raw silk prepared. Finally, the successful trial production of 48K large filament to 48K carbon fiber tow was realized. At the same time, the three-kilogram large tow carbon fiber prepared this time, the monofilament strength was significantly higher than the T300 carbon fiber level.
In the carbon fiber industry, it is usually called a large tow carbon fiber with more than 48,000 carbon fibers per strand (abbreviated as 48K). Compared to the current domestic large filament bundles composed of 1K-12K filaments. Carbon fiber, Shanghai Petrochemical's trial-produced products have achieved a single bundle of carbon fibers with more than 48,000 roots. Its greatest advantage is to significantly increase the carbon fiber single-line production capacity under the same production conditions, to achieve low-cost production, and to break the high price of carbon fiber. Application limitations.
At present, with the implementation of the standards for carbon fiber products, the quality of carbon fiber products of Shanghai Petrochemical has stabilized, and the output of products has gradually increased. At the same time that it has been approved by domestic users, it has also attracted the attention of foreign markets.
