Composite Support Structures for Cryogenic Systems
SCI’s advanced composite support structures are currently being utilized in numerous cryogenic systems. Advantages include low thermal conductivity, high strength and stiffness, lightweight, low outgassing, and integral fittings. Several types of fibers and resins are available to meet extreme structural and thermal requirements. Typical configurations including racetrack-shaped suspension bands, or straps, and tubular support posts with integral fittings, or struts. Design considerations for composite support straps for cryogenic systems are discussed. Common applications for composite support structures are dewar mounts for spacecraft, coolers for satellite instruments, and cryostat support such as superconducting magnets for medical imaging1.
