Abstract : The use of filament-wound fiber-glass liquid-hydrogen propellant tank structures should result in a considerable weight savings compared to conventional metal tanks providing that a suitable internal liner can be developed. This report investigates the use of plastic tape liners bonded to the inner surface of the filament-wound structure. The compatibility of liners, made of Teflon and Mylar tape, with respect to the filament-wound shell was studied experimentally using liquid hydrogen and theoretically using an analytical technique derived in this report. The investigation shows for bonded liners used at the temperature of liquid hydrogen (normal boiling point 20 deg K) that Teflon is incompatible with the filament-wound structure and Mylar is limited.
