Beijing Fangshuo Composite Materials Technology Co., Ltd. has achieved a critical phased breakthrough in the development of composite cryogenic common-bulk tanks. The custom cryogenic oxygen-inert material tailored for the tanks has completed technical development, with all performance metrics fully meeting design specifications. As an essential foundational material enabling the implementation of cryogenic common-bulk tanks, it delivers pivotal assurance for the overall R&D progress of the programme.

Composite cryogenic common-bulk tanks are core components for space vehicles, featuring extreme development difficulty, extended technical chains and intricate manufacturing workflows. In response to national aerospace strategic priorities, Fangshuo Composites has remained focused on high-end aerospace composite materials. The company launched early systematic R&D for tank development and assembled its core technical team to conduct end-to-end research spanning custom material formulation, integrated tank structural design, forming process optimisation and performance qualification & validation.

The cryogenic oxygen-inert composite serves as the primary substrate for cryogenic tank systems. Its material properties directly determine the tank’s service reliability and overall operational performance. To address harsh operating conditions of extreme low temperatures and oxygen-rich environments, the R&D team carried out targeted technical iteration and formulation refinement. Material specimens have passed authoritative third-party testing, and all key performance parameters satisfy design targets. The successful independent development of this material not only advances lightweight optimisation of aerospace structures and enhances the domestic supply and autonomy of critical aerospace materials, but also builds a robust technological moat for the company to deepen its presence in advanced aerospace materials and expand high-end aerospace supporting markets.

Going forward, Fangshuo Composites will steadily push forward the engineering development and iterative refinement of cryogenic common-bulk tanks, continuously strengthen its aerospace composite technology system, and foster high-quality innovative growth of China’s aerospace sector.
