China's carbon fiber industry stands at a subtle crossroads. On one hand, production capacity has ranked first globally for five consecutive years, an impressive figure. On the other, the battle for domestic substitution in high-end applications continues, with core technologies and equipment bottlenecks not yet fully resolved. The 8th Carbon Fiber Composites Industry Innovation and Development Exchange Conference, held in Lianyungang at the end of June 2026, provides a clear window into the industry's transition from 'big' to 'strong'.
Global Capacity Leader, But 'Big' Doesn't Mean 'Strong'
Industry data shows China's carbon fiber capacity has been the world's largest for five years, a milestone indicating undeniable basic supply capability. However, the conference's core discussions—technological breakthroughs, domestic substitution, and green production—reveal another reality: scale advantages have not fully translated into competitiveness in high-end markets. Applications in aerospace, new energy, and rail transit demand extremely high performance, stability, and consistency. In these areas, domestic carbon fiber still lags behind imports, with some key materials relying on foreign sources. Thus, the conference's goal of 'transforming from a production powerhouse to an industrial stronghold' represents a strategic recalibration: the next competition is not about who has more furnaces or longer production lines, but who has better technology, more stable processes, and broader downstream applications.
The Lianyungang Model: Full-Category Coverage and Industrial Chain Closure
The conference's location in Lianyungang was no coincidence. As a core carbon fiber industrial cluster, Lianyungang has built a complete chain from precursor production, carbonization, to composite application. More significantly, three world-class high-performance carbon fiber production lines have been commissioned, achieving full-category coverage of general-purpose, high-strength, and high-modulus types.
This means Lianyungang is no longer a single-category production base but can offer differentiated products for various downstream needs. For buyers, this full-category supply capability translates to shorter supply chains, lower logistics costs, and greater customization flexibility. For the industry, Lianyungang's model validates that a regional closed loop from raw materials to end-use is feasible, offering a replicable path for other regions.
Technological Breakthroughs vs. 'Bottleneck' Challenges
During the conference, academicians and corporate representatives engaged in deep discussions on technological breakthroughs. A consensus emerged: while China has made significant progress in basic capacity, it still lags in high-end, precision, and intelligent manufacturing. Equipment bottlenecks, particularly in oxidation and carbonization furnaces, directly limit product performance ceilings.
Green production emerged as a new critical issue. The high energy consumption and emissions of carbon fiber production are increasingly prominent under China's 'dual carbon' goals. The company that achieves low-carbon, low-cost mass production first will gain a competitive edge internationally. This is not just a technical issue but also a cost and market access one, as Western markets tighten scrutiny on supply chain carbon footprints.
Potential Impact on Downstream Procurement and Trade
China's expanding carbon fiber capacity is reshaping global supply and demand. For domestic buyers, this means more domestic substitution options and stronger bargaining power. However, high-end application certification cycles are long, and verification thresholds are high, so complete import substitution in the short term is unrealistic. Buyers should adopt a 'tiered substitution' strategy: prioritize domestic for general-purpose products, gradually verify for high-end ones.
For foreign trade companies, China's rising global capacity share means greater export leverage. But overseas markets are also raising requirements for product performance and environmental compliance. Enterprises should invest in carbon footprint accounting and green certifications to avoid future trade barriers.
