标准范围

本文件规定了一种试验方法，用于测定单搭接接头粘合组件中胶粘剂在承受拉力时的剪切性能。为了获得尽可能均匀的剪切应力分布，并将引发破坏的其他应力状态降至最低，试验在由厚的刚性粘附物组成的试样上进行，重叠长度较短。本试验方法可用于确定:-抗剪应力-胶粘剂失效的应变曲线；-胶粘剂的剪切模量；-可从应力/应变曲线得出的其他粘合性能，如割线剪切模量和最大剪切应力；-温度、环境、测试速度等对这些性能的影响。本文件不适用于粘合失败的情况。

This document specifies a test method for determining the shear behaviour of an adhesive in a single lap joint bonded assembly when subjected to a tensile force.The test is performed on specimens consisting of thick, rigid adherends, with a short length of overlap, in order to obtain the most uniform distribution of shear stresses possible and to minimize other stress states which initiate failure.This test method may be used to determine:— the shear-stress against shear-strain curve to failure of the adhesive;— the shear modulus of the adhesive;— other adhesive properties that can be derived from the stress/strain curve such as secant shear modulus and maximum shear stress;— the effect of temperature, environment, test speed, etc., on these properties.This document does not apply in case of adhesion failure.
