Abstract : The use of filament-wound fiber-glass liquid-hydrogen propellant tank structures should result in a considerable weight savings providing that a suitable internal liner can be developed. This report investigates the use of free-floating liners (not bonded to the inner surface of the filament-wound shell). A theoretical analysis and experimental study on laminated Mylar, Teflon, and aluminum-Mylar liners showed that upon tank pressurization at liquid-hydrogen temperatures, plastic liners fabricated to the internal dimensions of the filament-wound structure would fail in tension before the burst pressure of the filament-wound shell was approached.
