China's carbon fiber industry is entering a new scale of capacity competition. On June 28, CNBM commissioned three world's largest carbon fiber production lines at its Lianyungang base, covering high-strength, high-modulus, and large-tow technical routes. This marks not just a single enterprise's capacity leap, but an accelerating shift for domestic carbon fiber from 'capable of production' to 'full-spectrum, large-scale, low-cost' manufacturing.
Capacity Matrix: A Triple Jump from Lab to Industrialization
The three lines form a clear 'high-strength, high-modulus, large-tow' product matrix. The first line is the world's largest 1,000-ton-per-year SYT70 (T1100-grade) high-strength carbon fiber, targeting aerospace lightweighting and high-load demands. The second is a 5,000-ton-per-year SYT45S-48K large-tow fiber for cost-sensitive industrial applications like wind turbine blades and new energy vehicles. The third is a 600-ton-per-year M40-grade high-modulus line serving deep-sea/space equipment, high-end sports gear, and 3C electronics.
The total annual capacity of these three lines reaches 6,600 tons, while the entire Lianyungang base plans a total capacity of 31,000 tons with a 6 billion yuan investment across 1,500 mu and ten full lines. The first batch achieved 'production-ready' standards within one month of trial operation, indicating that the process maturity has moved from 'mass-producible' to 'stable mass production.' For downstream buyers, this means the historic pain points of 'technology without volume' and 'volume without stable quality' are being systematically resolved.
Industry Impact: Price Expectations and Supply Chain Restructuring
Carbon fiber is known as the 'king of materials,' but its core bottleneck for large-scale application has long been price. Domestic T700-grade carbon fiber once cost 20%-30% more than international peers, while higher grades like T1100 and M40 were almost entirely imported. With the volume release from Zhongfu Shenying's Lianyungang base, the market supply-demand landscape is fundamentally changing.
First, large-tow carbon fiber scaling will directly lower material costs for wind power and new energy vehicles. For wind turbine blades, where carbon fiber accounts for about 15%-20% of blade cost, a 30% price drop in domestic large-tow could reduce total turbine cost by 5%-8%, a substantial benefit for the price-sensitive wind industry. Second, high-end product localization will force international suppliers to lower prices while shortening supply lead times for aerospace customers. The previous 6-month-plus import cycle could shrink to 1-2 months.
However, capacity expansion also brings risks. If downstream demand growth fails to keep pace, the carbon fiber industry may face temporary oversupply and price wars. By 2025, China's carbon fiber capacity exceeded 100,000 tons, while actual demand was only about 80,000 tons, with capacity utilization below 80%. New lines will intensify this imbalance, forcing companies to seek premium space in higher-end, niche applications.
Regional and Policy Synergy: Lianyungang's Industrial Cluster Effect
The Lianyungang base is not an isolated project. The Jiangsu provincial vice governor explicitly pledged full support for carbon fiber industry development during the commissioning event, including building regular upstream-downstream docking mechanisms and creating open shared innovation platforms. This positions Lianyungang as a new carbon fiber highland alongside Jilin and Weihai.
From a supply chain perspective, carbon fiber involves upstream acrylonitrile raw materials, spinning equipment, and carbonization furnaces; midstream precursor and carbonization production; and downstream prepreg and composite processing. The Lianyungang base's scale will attract supporting enterprises to form a short-chain closed loop from raw materials to carbon fiber to composites to applications. For nearby textile companies, especially those in industrial textiles and composite weaving, this represents an opportunity to enter high-value-added segments.
