Abstract : In this report we present the results of an analytical (finite element) and experimental investigation of the stress-strain response of a composite cylinder subjected to an internal pressurization cycle. The composite cylinder is constructed of a steel liner and a graphite-bismaleimide outer shell. Results are also presented for cases where the structure was subjected to a temperature cycle above the manufacturer's specified operating temperature. The results indicate a delayed strain response in the composite outer shell and only small changes in burst pressure and strain-to-failure for temperature cycles up to 200 F higher than the manufacturer's specified temperature.
