Abstract : The use of fiber-glass-reinforced plastics as a structural material, in conjunction with internally located foam insulation for liquid-hydrogen propellant tanks, was investigated by designing, fabricating, and experimentally evaluating a subscale tank. The tank consisted of three main components: a structural shell of filament-wound fiber glass, an internal insulation system of polyurethane foam encapsulated in a vacuum-tight jacket of aluminum-Mylar-aluminum foil laminate, and an impermeable liner of the same laminate. Liquid-hydrogen boiloff tests were used to determine the thermal performance and pressure-cycling tests were used to evaluate structural performance.
