The Development Status of Composite Materials and Winding Process of Type IV Hydrogen Storage Cylinder

Review The Development Status of Composite Materials and Winding Process of Type IV Hydrogen Storage Cylinder Jinying Wu 1, Rui Wang 1, Ruisheng Liu 2, and Zhuo Zhang 1,* 1 College of Mechanical and Vehicle Engineering, Linyi University, Linyi 276000, China 2 Linyi Power Supply Company of State Grid, Linyi 276005, China * Correspondence: zhangzhuoqust@163.com Received: 27 September 2024; Revised: 2 March 2025; Accepted: 6 March 2025; Published: 19 March 2025 Abstract: In the context of the energy crisis, hydrogen energy has become a key research object in various countries due to its advantages. This article introduces the selection and molding process of Type IV hydrogen storage bottle liner materials, intermediate and surface fiber materials, winding methods and process selection, and constructs the components of the entire production process, describing the current development status of hydrogen storage bottles. By elaborating on the preparation process and materials used for Type IV hydrogen storage bottles, it is pointed out that current materials and safety have significant limitations on the development of hydrogen storage bottles, and the direction of lightweight and low-cost development is clarified. We hope that this article can help China’s Type IV hydrogen storage bottles achieve complete independence as soon as possible.
