Abstract

This paper presents a mechanical analysis method of carbon fiber wound aluminum lined high pressure hydrogen storage vessel. Based on simplifying the carbon fiber wound layer on the cylinder, two submodels are created. The stress formulas of carbon fiber wound layer on the cylinder are obtained by the submodels and the basic principle of elastic mechanics. In manufacturing process, the tensile force of fiber will be controlled in order to get prestresses in the aluminum liner. The prestress can lower the stress of aluminum liner under operating pressure and reduce the probability of stress corrosion accordingly. It can also improve the fatigue life.
