On October 10th, the first domestic production line of China's first 10,000-ton 48K large-tow carbon fiber project was put into operation in SPC’s Carbon Fiber Industry Base, and qualified products were produced. The product performance was comparable to that of the same level products abroad, and the quality reached the international advanced level, which marks the success of SPC's large bundle carbon fiber from key technology breakthrough, industrial trial production and industrialization to large-scale and localization of key equipment.

In the carbon fiber industry, those with more than 48,000 carbon fibers per bundle (48K for short) are usually called large tow carbon fibers. This 48K tow carbon fiber domestic line can realize large-scale and high-quality production. The project adopts PAN (Polyacrylonitrile)-based tow precursor and carbon fiber technology independently developed by SPC, and will be implemented in two stages. It is planned to be completed and put into operation in 2024, with a total capacity of 24,000 tons/year precursor and 12,000 tons/year large-tow carbon fiber.
