Carbon Fiber Prepreg Capacity Expansion Accelerates, a Key Variable for Aerospace Composites Supply Chain

When carbon fiber prepreg begins to be widely used in the fuselage structures of commercial aircraft, its lightweight and high-strength properties directly determine fuel economy and flight safety. Now, the localization of this key material is accelerating in the Yangtze River Delta.

Event Background

Jiangsu Ausheng Composite Materials Technology Co., Ltd.'s provincial major project has fully entered the phase of interior decoration and equipment installation, with full production expected within the year. Initiated in 2024, the project focuses on high-performance prepregs, structural component design and production, and UAV assembly, covering carbon fiber fabrics, prepregs, and composite parts for aviation.

From a construction pace perspective, only about two years from groundbreaking to production is highly efficient in the aviation materials sector. After commissioning, the project will prioritize the production of carbon fiber fabrics and prepregs, meaning a substantial increase in domestic high-end prepreg supply.

Industry Impact

Carbon fiber prepreg is aptly called the "skeleton" of aircraft, as its quality directly determines structural strength and fatigue life. For a long time, the domestic aviation-grade prepreg market has been dominated by a few international giants, with local enterprises mostly focusing on mid-to-low-end industrial grades. The Ausheng project will effectively fill the high-end capacity gap and reduce downstream OEMs' dependence on imported materials.

For the supply chain, capacity expansion implies a reshaping of price expectations. As domestic prepreg supply increases, the cost of aviation composite parts is expected to decline in the medium and long term, benefiting domestic UAV manufacturers and the civil aviation supply chain. Meanwhile, the UAV assembly business will help form a vertical integration effect of "materials-components-aircraft," enhancing regional industrial synergy.

For the Yangtze River Delta carbon fiber cluster, this project will strengthen the position of Wujiang in aviation composites, attracting more upstream and downstream enterprises and fostering a collaborative innovation ecosystem.

From a foreign trade perspective, the release of domestic high-end prepreg capacity may not only substitute imports but also potentially export to emerging aviation markets such as Southeast Asia and the Middle East. However, companies must pay attention to international airworthiness certification barriers and prepare relevant qualifications in advance.

Practical Recommendations

For Buyers - Monitor the project's production timeline and establish communication channels with Ausheng Technology early to secure trial order opportunities. - Compare domestic and imported prepregs in terms of performance, batch stability, and certification progress, and develop substitution verification plans. - Leverage the bargaining space brought by capacity expansion to add price adjustment clauses in annual procurement contracts.

For Foreign Trade Enterprises - Research the entry requirements for aviation-grade prepregs in target markets and prioritize countries with mutual airworthiness recognition agreements with China. - Collaborate with domestic material suppliers to participate in international aviation material exhibitions and expand customer base with combined "material + component" solutions. - Pay attention to the export window after domestic capacity release and prepare technical documentation and sample kits in advance.
