本文件规定了使用剪切试验装置测量纤维取向为0°和0°\/90°的连续纤维增强塑料复合材料的面内剪切应力\/剪切应变响应、剪切模量和剪切强度的方法。该方法适用于单向织物\/非织造织物和\/或织物包括单向织物制成的热固性和热塑性基体层合板，纤维以0°和0°\/ 90°取向于试样轴，其中铺层在试样中间平面上是对称的和平衡的。该方法适用于线性和非线性荷载变形范围内的剪切特性测定，即使剪切应变大于5%。短纤维和长纤维增强塑料复合材料也可以使用本文件进行测试。

This document specifies a method 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 applicable to 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 nonlinear load-deformation range even at shear strains greater than 5 %. Short and long fibre-reinforced plastic composites can also be tested using this document.
