ISO DIS 20337

Description / Abstract: This ISO standard specifies a method of using a shear test apparatus for measuring the in-plane shear stress/shear strain response, shear modulus and shear strength of continuous-fibre-reinforced plastic composite materials with fibre orientations of 0° and 0°/90°.

This method is suitable for use with thermoset and thermoplastic matrix laminates made from unidirectional layers/non-woven fabrics and/or fabrics including unidirectional fabrics, with the fibres oriented at 0° and 0°/90° to the specimen axis, where the lay-up is symmetrical and balanced about the specimen mid-plane.

The method is suitable for determining shear properties in both the linear and non-linear loaddeformation range even at shear strains greater than 5 %.
