Abstract
This paper investigates the effect of winding angle on composite overwrapped pressure vessel (COPV) manufactured by filament winding process where continuous fibers impregnated in resin and wound over a liner. Three dimensional shell model is considered for the structural analysis of pressure vessel. The study on COPV is carried out by considering carbon T300/epoxy material. The thickness of composite vessel is calculated by using netting analysis. The study focused on optimum winding angle, total deformation, stress generation and failure analysis of composite pressure vessel. The failure of COPV is predicted by using Tsai-Wu failure criteria. The classical laminate theory (CLT) and failure criteria is considered for analytical method and obtained results are compared with numerical results which are obtained from ANSYS workbench (ACP) for validation. This comparison further helps in predicting behavior of COPV for change in winding angle and operating internal pressure.
