Three new composite laminates have been developed for use as structural supports, thermal insulation in cryogenic and radiation environments. Boron-free, woven glass cloth has been preimpregnated with three types of resin systems. The organic resin systems are multifunctional and are much less sensitive to radiation than the epoxy systems used in G-10CR and G-11CR. The laminates are fabricated by curing the preimpregnated glass cloth under high pressure to produce higher glass content (70-74 vol. %). Higher glass content is beneficial because (1) it increases the laminate strength and stiffness; (2) it leads to more isotropic composite properties; and (3) it increases the overall radiation resistance because half and the amount of organic resin content is used. The cost of at least one of the laminates is comparable to that of G-10CR. Elastic, short-beam shear, thermal contraction, and flexural properties have been measured.
