While the global aviation composites market remains dominated by Toray, Hexcel, and other giants, the planned full operation of a provincial-level project in China sends a strong signal of supply chain restructuring. Jiangsu Ausheng Technology's civil aviation composites project in Wujiang is expected to achieve full production this year, covering carbon fiber fabric, high-performance prepreg, and aviation composite parts. This is not merely an addition of capacity but signifies a qualitative leap in China's independent control over the critical aviation-grade prepreg segment.
Background
The project, initiated in 2024, has entered the phase of interior decoration and equipment installation and will prioritize the production of carbon fiber fabric and prepreg raw materials. As a provincial major project, its short construction cycle and rapid progress reflect the collaborative efficiency between local government and enterprises in strategic emerging industries. From a product perspective, carbon fiber prepreg is often referred to as the 'skeleton' of aircraft structures, directly determining the strength and lifespan of aviation components. For a long time, China's high-end prepreg has heavily relied on imports, becoming a bottleneck restricting the development of the aviation composites industry.
Ausheng's choice of Wujiang is not accidental. The Yangtze River Delta boasts a complete chemical fiber and textile industry chain, with accumulated processing experience in downstream carbon fiber applications. As a textile hub, Wujiang faces pressure to transform from traditional textiles to high-performance fiber composites, and this project provides a fulcrum for regional industrial upgrading. For buyers, this means the supply radius for aviation-grade prepreg will be significantly shortened, greatly improving lead times and cost controllability.
Industrial Impact
From an upstream perspective, the project directly benefits carbon fiber precursor suppliers. The expansion of prepreg capacity will drive demand for T700-grade and above carbon fibers, allowing domestic carbon fiber companies to expand their market share in the aviation sector. Additionally, the project includes drone final assembly, indicating the accelerated convergence of low-altitude economy and aviation composites. Carbon fiber structural parts will gain more solid material support in emerging applications such as eVTOL and industrial drones.
For downstream aviation manufacturers, the batch supply of domestic prepreg will break the passive situation of 'material bottleneck.' Previous pain points such as long procurement cycles, price volatility, and slow technical response caused by reliance on imported materials are expected to ease with the release of local capacity. However, capacity does not equate to quality. Aviation-grade prepreg requires extremely stringent control over resin formulation, fiber wetting, and volatile content. Whether Ausheng can pass airworthiness certification and achieve stable mass production remains a focal point for industry observation.
From a competitive landscape, this project will intensify differentiation in the domestic prepreg market: competition in low-end industrial-grade products is already fierce, while a significant gap remains in high-end aviation-grade products. If Ausheng can reach full production within the year, it will directly fill part of the high-end capacity gap and set a demonstration effect for other enterprises planning to enter this field. Regionally, Wujiang is expected to transform from a traditional textile base to a high-performance composites industry highland, driving the collaborative upgrading of surrounding weaving, coating, testing, and other related sectors.
