China's largest single-line capacity large-tow carbon fiber production line was put into operation on Friday in Ordos City of north China's Inner Mongolia, according to Chinese oil giant Sinopec.
With a designed single-line capacity exceeding 3,000 tons, the products are said to reach internationally advanced performance levels, marking another key step toward high-end carbon fiber development in China.
The overall plan calls for the construction of 10 production lines.
The first-phase project currently put into operation includes two production lines, while the second-phase project, comprising eight additional lines, is expected to be fully completed by the end of 2027. When completed, the project's overall production capacity is expected to reach 30,000 tons.
Carbon fiber offers outstanding mechanical performance. Its density is less than one quarter of steel, while its strength is seven to nine times that of steel. It also exhibits strong corrosion resistance, making it widely used in sectors such as aerospace, new-energy vehicles and high-end equipment.
In the carbon fiber industry, fibers with more than 48,000 filaments per tow are classified as large-tow carbon fiber. Compared with small-tow carbon fiber, the most significant advantage of large-tow carbon fiber lies in its ability to achieve higher single-line output and lower production costs under the same production conditions. This translates into clear benefits for large-scale industrial adoption.
