纤维增强塑料复合材料 - 剪切试验方法 使用剪切框架测定面内剪切应力/剪切应变响应和剪切模量

[中文适用范围]： 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。 该方法适用于由单向层/无纺布和/或包括单向织物的织物制成的热固性和热塑性基质层压材料，其中纤维定向于与试样轴成0°和0°/90°，其中铺层关于样本中平面对称且平衡。 该方法适用于确定线性和非线性载荷变形范围内的剪切特性，甚至在剪切应变大于 5% 的情况下也是如此。 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。 [外文原描述]： 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.
