Filament Wound Composite Thermal Isolator Structures for Cryogenic Dewars and Instruments

Source

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.
