Abstract : The stress/strain behaviour of a unidirectional Kevlar/epoxy resin composite system under each of five uniaxial stress states has been determined experimentally. The responses of the unreinforced epoxy resin to three uniaxial stress states have also been determined. The excellent longitudinal tensile properties, combined with low density of this composite system allow the design of structures which are significantly more weight efficient than similar structures made from an 'E' glass/epoxy system. However, the relatively poor compressive and transverse tensile properties make Kevlar/epoxy composites unsuitable for applications where significant compressive or bending loads are expected.
