When aviation-grade carbon fiber prepreg still relies heavily on imports, a major provincial project in China is poised to change that landscape. Jiangsu Aosheng Composite Technology Co., Ltd. is building a civil aviation composite materials project in Wujiang, Suzhou, expected to be fully operational this year, focusing on high-performance prepreg and structural components. For the domestic aviation supply chain, this is not just additional capacity but a revaluation of cost and supply security.
Project Positioning and Capacity Release
The project, initiated in 2024, has now entered the interior renovation and equipment installation phase, marking a critical shift from construction to production. It focuses on three areas: high-performance prepreg, structural component design and manufacturing, and drone final assembly. Prepreg is a core intermediate in the carbon fiber composite chain, often described as the 'skeleton' of aircraft structures, directly affecting the mechanical properties and reliability of downstream parts.
Upon completion, the plant will prioritize production of carbon fiber fabric and prepreg, indicating Aosheng's strategy to enter from the upstream of the value chain rather than directly into final component manufacturing. This approach helps quickly establish stable raw material supply and accumulate process data for future structural parts. For buyers, once domestic prepreg reaches scale, there will be significantly more room for price negotiation.
From an industry supply-demand perspective, China's carbon fiber capacity has grown to among the world's largest, but a gap remains in aviation-grade prepreg, especially high-modulus and high-toughness products, which have long depended on suppliers like Toray. Aosheng's project will increase domestic self-sufficiency, shorten lead times, and may prompt similar capacity expansions by competitors.
Industrial Impact and Transmission Effects
The expansion of prepreg capacity will transmit effects upstream to precursor and carbon fiber production, and downstream to aviation parts and drone manufacturing. Upstream, prepreg production demands high consistency in carbon fiber quality, pushing domestic producers to optimize processes to meet aviation standards. Meanwhile, large-scale procurement will reduce unit costs, driving prepreg prices down.
For midstream processors, the installation and commissioning phase often involves trial production and certification, bringing orders for surrounding mold, tooling, and testing services. Wujiang, as a manufacturing hub in the Yangtze River Delta, has advantages in precision machining and supply chain coordination. The project is likely to foster a new composite materials cluster, attracting upstream and downstream enterprises to locate nearby.
For foreign trade companies, especially exporters of drones and general aviation components, a stable domestic prepreg supply means avoiding delivery risks and exchange rate fluctuations associated with imported materials. Moreover, the localization of aviation composites may change international buyers' perception of 'Made in China,' shifting from low-cost assembly to high-tech component supply.
