China's carbon fiber industry has once again stepped on the accelerator in the race towards both scaling up and moving up the value chain. On June 28, CNBM commissioned three production lines in its Lianyungang base, each claiming the title of the world's largest in its category. The lines cover T1100-grade high-strength carbon fiber, 48K large-tow carbon fiber, and M40-grade and above high-modulus carbon fiber, creating a full-spectrum manufacturing capability. This move fundamentally challenges the long-standing dependence on imports for high-end carbon fiber supply in China.
Background
The Lianyungang carbon fiber base, initiated in June 2023, covers 1,500 mu (about 100 hectares) with a total planned investment of 6 billion yuan and a design capacity of 31,000 tons per year, planned to accommodate ten full-capability lines. The first three lines have achieved 'commissioning and qualification' within a month of trial operation. Each line targets a distinct market: the 1,000-ton SYT70 (T1100-grade) line serves the aerospace sector's demand for lightweight and high-load-bearing materials; the 5,000-ton SYT45S-48K large-tow line aims to provide cost-effective materials for wind power and new energy vehicles; and the 600-ton M40-grade and above high-modulus line serves deep-sea/deep-earth equipment, high-end sports gear, and 3C electronics.
From an industrial layout perspective, CNBM's choice of Lianyungang, Jiangsu Province, is strategic. Jiangsu Vice Governor Shen Jianrong stated at the launch event that the province will fully support the carbon fiber industry, promoting regular exchange mechanisms and building open innovation platforms. This suggests that the Lianyungang base will serve not only as a production hub but also as a center for technology and supply chain collaboration, radiating influence across the entire carbon fiber ecosystem.
Industry Impact
For the textile industry, the scaling up of carbon fiber production is not an isolated event. It reshapes the upstream raw material supply and downstream composite processing segments. Over the past years, domestic demand for carbon fiber has grown rapidly, but high-end products like T1100-grade and M40-grade have heavily relied on imports from Toray and others, exposing the supply chain to price volatility and geopolitical risks. The commissioning of these full-spectrum lines directly fills the gap in domestic mass production of T1100-grade and high-modulus carbon fiber, providing a stable and controllable domestic alternative for aerospace, wind power, and automotive lightweighting.
From a cost perspective, the mass production of large-tow carbon fiber (48K) is key to lowering the barrier for industrial applications. For wind turbine blades, carbon fiber can significantly reduce weight and improve fatigue life, but its high cost has limited its use to premium models. The 5,000-ton SYT45S-48K line, once at full capacity, will effectively lower the market price of industrial-grade carbon fiber, driving its adoption from 'feasible' to 'large-scale' in wind power and new energy vehicles. For downstream players in carbon fiber prepreg, fabric, and composite manufacturing, this means more abundant and predictable raw material supply, facilitating long-term product planning and cost control.
Notably, Sun Shaobin, deputy director of the SASAC's Science and Technology Innovation Bureau, emphasized at the event that achieving self-reliance and advancing to the high-end in carbon fiber is a shared mission for central enterprises. This signals strong policy support for carbon fiber as a strategic new material, with expected continued investment in R&D, standard setting, and application demonstration. For all companies in the carbon fiber value chain—from upstream precursor producers to downstream composite processors—this means faster technology cycles and intensified competition.
