Abstract

This study focuses on a 70 MPa Type IV hydrogen storage cylinder and investigates optimization of the fiber-winding process and static-strength behavior through finite element simulation. Based on composite laminate design theory, the thickness distribution of the winding layer in the dome region was predicted. A finite element model consisting of a plastic liner, a metal boss, a carbon-fiber winding layer, and a glass-fiber protective layer was established. The stress distribution of each component under the rated high-pressure condition was systematically analyzed. The results show that the components exhibit good cooperative load-bearing behavior. The stress of the metal boss basically satisfies the strength requirement, and the composite winding layer demonstrates favorable load-bearing capacity.
