Low-Temperature Properties Of A Unidirectionally Reinforced Epoxy Fiberglass Composite

The tension, compression and in-plane shear properties of a unidirectionally reinforced fibre/epoxy composite were measured at 295, 76 and 4 K. The composite plate material was produced by the wet-filament winding method. The orthotropic material properties are dominated by the glass fibre properties when measured parallel to the direction of reinforcement, and they are dominated by the epoxy resin matrix properties when measured transverse to the reinforcement. All the values of strength and elastic moduli increased as the test temperature decreased.
