Carbon fiber prepreg, a critical aerospace material long dominated by overseas giants, is now entering an accelerated phase of domestic substitution. Jiangsu Ausheng Composite Technology Co., Ltd. has initiated the interior renovation and equipment installation phase for its civil aviation composite project in Wujiang, Suzhou, with full production expected within this year. This provincial-level major project signals a substantial shift in the supply landscape of aviation-grade prepreg in China.
Project Core and Capacity Direction
The project, launched in 2024, focuses on high-performance prepreg, structural component design and production, and drone final assembly. Its products cover carbon fiber fabric, high-performance prepreg, and aviation composite parts. Among these, carbon fiber prepreg is regarded as the "skeleton" of aircraft structures, with its lightweight, high-strength, fatigue-resistant, and corrosion-resistant properties directly determining structural performance and lifespan.
From a capacity perspective, the project will prioritize the production of carbon fiber fabric and prepreg, indicating that the upstream material supply bottleneck will be addressed first. For downstream manufacturers of structural components and drones, this means not only enhanced supply chain stability but also potentially significant reductions in procurement costs.
Industrial Impact: From Material Autonomy to Cost Restructuring
In the cost structure of aviation composites, prepreg often accounts for more than half. For a long time, China's aviation-grade prepreg has been heavily reliant on imports, with volatile prices and long lead times, creating an invisible ceiling for the domestic aircraft and drone industries. Ausheng's project will directly increase the domestic supply of aviation-grade prepreg, potentially breaking the pricing power of overseas suppliers and driving material prices to more reasonable levels.
For buyers, this means greater bargaining power and lower supply chain risks. Previously, aerospace manufacturers often had to lock in orders with overseas suppliers half a year or even a year in advance. With local capacity coming online, procurement cycles could shorten to a few months. Moreover, local suppliers' advantages in responsiveness and customization will foster collaborative innovation across the aviation composites chain.
For upstream carbon fiber precursor suppliers, this project sends a clear demand signal. Aviation-grade prepreg requires extremely high-quality carbon fiber, and Ausheng's capacity ramp-up will drive demand for high-performance carbon fiber, encouraging domestic precursor manufacturers to upgrade their processes, forming a complete loop from precursor to prepreg to structural parts.
Regional Cluster and Supporting Opportunities
Wujiang, as an important textile and new materials cluster in the Yangtze River Delta, will further strengthen its industrial depth in new materials with this project. The surrounding area has a mature supporting system for chemical fiber, weaving, and dyeing. Although the technical barriers between aviation composites and civil textiles are significant, there is potential for technology transfer and equipment sharing in processes like fabric weaving and resin impregnation.
For existing textile enterprises in the region, this is both a window for cross-industry learning and an opportunity for industrial upgrading. The weaving of aviation-grade carbon fiber fabric shares many similarities with high-end industrial and technical textiles, and companies with relevant technical expertise may enter the aviation supply chain.
