Optimization of Composite Pressure Vessel

In this study, optimal angle-ply orientations of symmetric and antisymmetric shells designed for maximum burst pressure were examined. Burst pressure of filament wound composite pressure vessels under alternating pure internal pressure was investigated. The study deals with the winding angle on filament wound composite pressure vessels. Finite element method was employed to verify the optimum winding angles. The solution was presented and discussed for various orientation angles. Glass reinforced plastic (GRP) was manufactured by E-glass-epoxy fiber. The specimen had ten layers which had various orientation angles. The layers were oriented symmetrically and antisymmetrically for, [45/-45/90/45] orientations. The finite element solution was obtained using commercial software ANSYS 11.0.
