    Studies showing high tensile strength, low thermal conductivity, and adequate fatigue strength capabilities in conjunction with low resin outgassing properties of S-901 fiber glass with SCI REZ 080 and 081 epoxy resins has resulted in use of filament wound tension straps, struts, and conical shells as thermal isolators in several high-performance cryogenic applications. These thermal isolator structures and their use in the following cryogenic systems are discussed in this paper: hydrogen and oxygen dewars for space shuttle, helium tank for the infra-red astronomy satellite, spacecraft refrigerators, and infrared telescope. Mechanical and thermo-physical properties of the composite laminates are presented.
