The low thermal conductivity of graphite-reinforced epoxy laminates in the 77-4 K range combined with high strength and modulus suggests that it is possible to fabricate thermal isolation supports more efficient than those which use metals. This study details the effect of cryogenic temperatures on two types of graphite-reinforced epoxy-matrix laminates. One is fabricated with fibers of intermediate strength and intermediate modulus; the other is fabricated with a fiber of lower strength but high modulus. Results of tests on a composite laminate reinforced with an aramid fiber are also presented. The study evaluates the uniaxial longitudinal strength and moduli (6 ply), the uniaxial transverse strength and moduli (15 ply), uniaxial longitudinal and transeverse compressive strength (30 ply), and in-plane shear strength and moduli (45 degrees, 10 ply). Tables and graphs are included. The study confirms that off-the-shelf laminates developed for room-temperature service are viable engineering materials for use at 4 K.
