精细陶瓷（高级陶瓷 高级技术陶瓷） 增强材料的试验方法 用热夹持技术测定空气中高温下陶瓷长丝的拉伸性能

[中文适用范围]： 本标准规定了在高温空气中使用热夹持技术测定陶瓷长丝的拉伸性能（如拉伸强度、杨氏模量和断裂应变）的试验方法。本标准适用于从多丝束或线轴获得的连续陶瓷长丝。本标准不适用于在试验温度下具有蠕变行为的陶瓷长丝。热夹持技术受当前陶瓷粘合剂温度耐受性的限制。 [外文原描述]： This document specifies a test method for determination of tensile properties, such as tensile strength, Young’s modulus, and fracture strain of ceramic filaments at elevated temperature in air using the hot grip technique. This document applies to continuous ceramic filaments obtained either from a multifilament bundle or spool. This document does not apply to ceramic filaments with creep behaviour at test temperature. The hot grip technique is limited by the temperature resistance of the current ceramic adhesive.
