Abstract : The use of filament wound fiberglass liquid hydrogen propellant tank structures should result in a considerable weight savings providing that a suitable internal liner can be developed. This report investigates a liner made of a matrix of glass flakes and epoxy resin bonded to the inner surface of a filament wound shell. A possible liner fabrication technique was developed. When tested with liquid hydrogen the glass flake liner was shown to be thermally compatible with the filament wound shell. However, no conclusion could be made concerning strain compatibility because the tank could not be tested at a pressure greater than 1 atmosphere due to leaks.
