Thin-Metal Lined PRD 49-III Composite Vessels.
Abstract
In this program a total of 22 - 8 in diameter PRD-49-3 filament wound vessels were evaluated for burst strength and fatigue performance. Eighteen vessels contained a 0.003 in (0.0762 mm) thick 321 stainless steel liner for fluid containment while the remaining four had elastomeric liners. Six of the metal-lined tanks were burst tested at +70 deg F (+21 deg C). The final vessel design with a metallic liner gave an average burst pressure of 2560 psi and an average performance factor (PV/W) of 1.75 x 10 to the 6th inch. Twelve metal-lined vessels were cycled at strain levels equivalent to 50% and 75% of ultimate at +70 F (+21 C) All these vessels leaked in a relatively few cycles (20-60 cycles) with failure occurring in all cases in the metallic liner. The thin liner would de-bond from the composite and buckle during depressurization. No composite failures or indications of impending composite failures were obtained in the metal-lined vessels.
