This paper presents results of stress calculations of a filament wound pressure vessel by using the finite-element method and theoretical calculations based on both the netting theory and laminar theory. Composite vessels were fabricated by winding high-strength fiber-glass-impregnated-epoxy-type resin on Al alloy liners. The winding was conducted in two modes : helical winding and hoop winding. The vessel consisted, therefore, of three layers : the metallic liner layer, the helical winding layer, and the hoop winding layer. Before the service operation, vessels were subjected to autofrettage, an overpressuring treatment, in order to produce compressive residual stresses in the metallic liner and to increase the fatigue life of the liner. Analysis of cyclic deformations of the composite vessel was performed in order to simulate the loading steps after fabrication: autofrettage, service operations, and burst. The results of calculations were compared with experimental results.
