纤维增强复合材料 用微机械单纤维拔出试验测量界面剪切强度

[中文适用范围]： 本文件规定了一种通过拔出试验测定单纤维与基体之间的界面剪切强度的方法。该方法可用于测量临界能量释放率。该方法适用于碳纤维、玻璃纤维、玄武岩纤维和类似刚性增强纤维以及热固性、热塑性和细粒混凝土基体。其还可用于聚集体增强纤维和其他无机基体。本文件不适用于以下情况：a)弹性纤维及弹性基体，例如橡胶；b)在高于 400°C 的温度下固化或融化的基体；c)在样品制备过程中有明显气泡形成或膨胀趋势的基体；d)泡沫材料。 [外文原描述]： This document specifies a test method for determining the interfacial shear strength between a single fibre and a matrix by means of a pull-out test. The method can be used to measure the critical energy release rate. The method is applicable to reinforcement fibres, such as carbon fibres, glass fibres, basalt fibres and similar stiff reinforcement fibres and to thermoset, thermoplastic and fine-grained concrete matrices. It can be used for polymeric reinforcement fibres and for other inorganic matrices. It is not applicable to: a) elastomeric fibres and elastomeric matrices such as rubber; b) matrices which cure or melt at temperatures above 400 °C; c) matrices that show a strong tendency to bubble formation or expansion during the sample-preparation process; d) foams.
