ISO 19630:2017规定了测定陶瓷纤维单丝拉伸性能的条件,如拉伸强度、杨氏模量和断裂应变。该方法适用于从丝束、纱线、编织物和针织物中提取的连续陶瓷长丝,其断裂应变小于或等于5%。
该方法不适用于呈现非线性应力-应变曲线的碳纤维。该方法不适用于检查纤维强度特性的均匀性,也不适用于评估应力下体积的影响。不包括灯丝失效的统计方面。
ISO 19630:2017 specifies the conditions for the determination of tensile properties of single filaments of ceramic fibre such as tensile strength, Young modulus and fracture strain. The method applies to continuous ceramic filaments taken from tows, yarns, braids and knittings, which have strain to fracture less than or equal to 5 %.
The method does not apply to carbon fibres that exhibit nonlinear stress-strain curve. The method does not apply to checking the homogeneity of strength properties of fibres, nor to assessing the effects of volume under stress. Statistical aspects of filament failure are not included.
