Khalil and Han investigate, in this study, materials that are capable of being used in struts for large superconducting energy storage magnets. The candidate matrials that poses the requisite high strength-to-weight ratios and low thermal conductivities are fiberglass-epoxy and polyester composites. This investigation focuses on fiberglass-epoxy composites (G-10CR), on polyester fiberglass (Extren), and on glass-fiber-wound epoxy composite tubes (GFW AT-1008). The mechanical properties tested were the compressive strength, eslastic modulus, fatigue, and fracture behavior at 300 K and at 77 K. thermal conductivity, heat diffusivity, and specific heat were also tested in the temperature range of 4-300 K. Specifications for the samples, the test equipment, and the procedures are given, along with tables and photographs of the results. Calculation methods for various properties are described. A comparative evaluation of the materials is discussed.
