On June 28, 2026, China National Building Materials Group (CNBM) commissioned three carbon fiber production lines in Lianyungang, covering T1100-grade high-strength, M40-grade high-modulus, and 48K large-tow industrial products. Each line claims 'world's largest' capacity, with a combined annual output of 6,600 tons, part of a broader base planned for 31,000 tons across ten lines. This is not a simple capacity expansion but a landmark event signaling China's carbon fiber industry moving from 'single-point breakthroughs' to 'full-spectrum coverage.'
Capacity Structure: From 'Filling Gaps' to 'Setting Standards'
Over the past decade, the core challenge for China's carbon fiber sector was 'existence'—whether it could reliably produce T700 and T800 grades. Now, the three lines in Lianyungang target three distinct application dimensions: the 1,000-ton SYT70 (T1100) line for aerospace lightweighting and high load-bearing; the 5,000-ton SYT45S-48K large-tow line for cost-sensitive industrial markets like wind turbine blades and new energy vehicles; and the 600-ton M40-plus high-modulus line for deep-sea exploration, premium sports equipment, and 3C electronics requiring high stiffness.
This 'high-strength, high-modulus, large-tow' matrix layout means Chinese carbon fiber firms are no longer passively filling import gaps but actively defining product gradients. According to public industry data, few global enterprises have simultaneously mass-produced all three categories at such scales. The Lianyungang base effectively reshapes global supply patterns, consolidating technical routes previously scattered across different countries and companies into a single production hub.
Downstream Impact: 'Material Dividends' for Textile Composites and New Energy
For the textile industry, carbon fiber is not a direct fabric material but the core skeleton for industrial textiles and composite reinforcements. The large-tow 48K carbon fiber's mass production primarily benefits wind blade manufacturers and automotive lightweighting. Previously, the high price threshold of large-tow carbon fiber limited its industrial penetration. The 5,000-ton line is expected to reduce per-ton costs by 15%-20%, directly lowering material costs for carbon beams in wind turbines and structural parts in new energy vehicles.
High-modulus carbon fiber applications lean toward high-end textile composites, such as carbon fiber bicycle frames, tennis rackets, fishing rods, and thin casings for 3C electronics, all requiring M40-plus grades for high rigidity. The 600-ton annual capacity, though modest in absolute terms, is sufficient to cover most domestic demand for premium sports equipment and consumer electronics, reducing reliance on overseas suppliers like Toray and Mitsubishi.
For aerospace, the localization of T1100-grade carbon fiber carries deeper significance. Previously, domestic high-strength carbon fiber was mainly T800-grade, with T1100 still in small-batch trial. The stable operation of a 1,000-ton line will support major projects like COMAC's C929 wide-body jet and next-generation military drones, while also boosting export competitiveness of intermediate products like carbon fiber prepregs and fabrics.
Industrial Chain Synergy: Can Lianyungang Become the 'Carbon Fiber Capital'?
At the commissioning event, Jiangsu Province's vice governor explicitly pledged to 'promote regular docking mechanisms between upstream and downstream industries.' This is not empty rhetoric. The Lianyungang base, covering 1,500 mu with a total investment of 6 billion yuan, will naturally attract downstream composite processing, equipment manufacturing, and testing certification firms to cluster. Located on the coast near the wind-power-dense East China region, and complementing Zhongfu Shenying's existing bases in Xining and Shanghai, Lianyungang has the geographic conditions to become a carbon fiber industrial hub.
Challenges remain. Carbon fiber production is energy-intensive and technologically demanding; green and digital transformation are necessary hurdles. The project claims 'immediate compliance upon commissioning,' with initial lines achieving stable production after just one month of trial runs, indicating high process maturity. However, as the remaining seven lines come online, maintaining product consistency, managing raw material (e.g., acrylonitrile) price volatility, and balancing capacity utilization with market demand are questions Zhongfu Shenying must continuously address.
