For cryogenic application, M40-level braiding fabric/epoxy composites were prepared via a RTM process. The mechanical properties of M40-level braiding fabric/epoxy composite at 80℃, RT and -196℃ were examined. The effects of cryogenic temperature on the mechanical properties of the composite were studied.
