The in-plane shear modulus and strength of fiber-reinforced plastic composites may be determined using the 45 degree tension test specified in ISO 14129. The method is suitable for use with thermoset and thermoplastic matrix laminates made from uni-directional layers and/or fabrics including uni-directional fabrics, with the fibers, oriented at ± 45 degrees to the specimen axis, where the lay-up is symmetrical and balanced about the specimen mid-plane.
