EVS-EN ISO 14129:2000

This International Standard specifies a procedure for determining the in-plane shear stress-shear strain, shear modulus and shear strength of fibre-reinforced plastic composites by the +/- 45° tension test method. The method is suitable f for use with the following materials: - thermoset and thermoplastic matrix laminates made from unidirectional layers and/or fabrics including unidirectional fabrics, with the fibres oriented at +/- 45° to the specimen axis. the lay-up shall be symmetrical and balanced about the specimen mid-plane.
