Autofrettage Pressure Analysis of Carbon-fiber Wound Composite Gas Cylinders
Despite the widening use of the carbon fiber wound composite gas cylinder, the research on its structure is mainly focused on the experiment method. In this paper, the APDL language in ANSYS was used to create a model of carbon fiber wound aluminum alloy liner composite gas cylinders with the thickness and the wound angle of both heads varied. The autofrettage process of the cylinder was analyzed and the range of autofrettage pressure value was determined by the DOT CFFC standard. It is expected that the finite element analysis results would be conducive to the engineering practice.
