Filament-reinforced cylindrical pressure vessels: analysis and numerical evaluation
The response to internal pressure of a cylindrical vessel consisting of a metal liner reinforced with a circumferentially wound filament-epoxy composite has been analyzed. Expressions for pressures required to produce the onset of yielding and complete yielding in the liner, failure of the composite, and efficiencies are derived for all combinations of three liner materials (HP-9-4-20 steel, 6061-T6 Al, and Ti-6Al-4V), and three composites (Kevlar 49-epoxy, Thornel 400-epoxy, and Thornel 75-epoxy). Failure pressures are highest for the Kevlar 49-reinforced vessels. At lower failure pressures, 6061-T6 Al/Kevlar 49-epoxy vessels are most efficient as measured by the product of failure pressure and interior volume divided by vessel mass.
