Abstract

The aim of present study was investigate the buckling pressure of moderately thick-walled filament-wound carbon–epoxy stiffened composite pressure vessel subjected to external hydrostatic pressure through finite element analysis and compare the result with un-stiffened filament wound carbon/epoxy composite pressure vessel used in under water vehicle applications. The winding angles were [±30/90] FW, [±45/90] FW and [±60/90] FW. ANSYS 14.0 APDL, a commercial finite element software package successfully predicted the buckling pressure of filament-wound composite pressure vessel with a deviation much higher than the results of un-stiffened filament wound composite cylinder .All the finite element analysis shows that the composite pressure vessel with winding pattern [±60/90] FW has the higher value of critical buckling pressure. Major failure modes in both the analysis were dominated by the helical winding angles.
