精细陶瓷（先进陶瓷 先进技术陶瓷） 增强材料的试验方法 常温下纤维丝的拉伸性能测定

[中文适用范围]： 本文件规定了在环境温度下测定陶瓷纤维等单丝拉伸性能（如拉伸强度、杨氏模量和断裂应变）的条件。本文件适用于从丝束、纱线、编织物和针织品中取出的连续陶瓷单丝，其断裂应变小于或等于5%。本文件不适用于表现出非线性应力-应变曲线的碳纤维。本文件不适用于检查纤维强度性能的均匀性，也不适用于评估应力下体积的影响。文中指出了强度统计参数的估计方法。 [外文原描述]： This document specifies the conditions for determination of the tensile properties of single filaments of ceramic fibre such as the tensile strength, Young modulus and fracture strain. This document applies to continuous ceramic filaments taken from tows, yarns, braids and knittings, which have strain to fracture less than or equal to 5 %. This document does not apply to carbon fibres that exhibit a nonlinear stress-strain curve. This document does not apply to checking the homogeneity of strength properties of fibres, or to assessing the effects of volume under stress. Methods of estimation of strength statistical parameters are indicated.
