Abstract

For the thermal insulation of cryogenic tanks in satellite applications fiber reinforced composite (FRC) materials are preferable because of their low thermal conductivity and high tensile strength compared to metallic materials. At the ISO-satellite the main liquid helium (LHe) tank is suspended by one spatial framework and eight pretensioned chain strands at each side. Frameworks and chain strands are acting as a thermal barrier and therefore made of FRC. To meet the various and, in parts contradictive requirements, sophisticated design approaches are chosen for the structural parts.
