Fibre-reinforced plastic composites in-Plane Shear Stress/Shear Strain Response of ISO 14129

EN ISO 14129: Fibre-reinforced plastic composites - Determination of the in-plane shear stress/shear strain response, including the in-plane shear modulus and strength, by the +/- 45° tension test method

This test is use tension test method to determine the shear strength, stress etc.,  tensile test of a ±45° laminate is used to determine the in-plane shear response of polymer matrix composite materials. Uniaxial tensile force is applied to a flat test specimen up to 5% shear strain to investigate the in-plane shear stress/strain response, and critical mechanical materials properties including shear modulus and shear strength. Composite materials addressed in this standard include thermoset and thermoplastic matrix laminates in the form of unidirectional layers or fabrics, with the fibres oriented at ± 45° symmetrical to the main specimen axis. The ± 45° in-plane shear test is performed by placing a test specimen in the grips of either a servohydraulic or an electromechanical testing machine and subjecting it to controlled tension load up to 5% shear strain. The specimen response can be measured with a contacting or non-contacting extensometer, or strain gages.

Test sample size: 250mm length, 25mm width, 2mm thickness. 

Machine recommend: UnitedTest electronic Universal testing machine 50Kn, 100KN.

Test fxiture recommend: UnitedTest hydraulic wedge tensile grips.
