精细陶瓷（先进陶瓷 先进技术陶瓷） 室温下陶瓷复合材料的力学性能 弯曲强度的测定

[中文适用范围]： 本文件规定了在室温下，使用三点或四点弯曲法测定连续纤维增强陶瓷基复合材料弯曲强度的试验方法。本文件适用于所有连续纤维增强的陶瓷基复合材料，包括单向（1D）、双向（2D）和三维（xD，其中2 < x ≤ 3）纤维排列形式，如ISO 19634中所定义，并沿一个主要增强方向轴加载。 [外文原描述]： This document specifies a test method for the determination of the flexural strength of ceramic matrix composite materials with continuous fibre reinforcement, under three-point or four-point bend at room temperature. This document is applicable to all ceramic matrix composites with a continuous fibre reinforcement, unidirectional (1D), bidirectional (2D), and tridirectional x D with (2 < x ≤ 3) as defined in ISO 19634, loaded along one principal axis of reinforcement.
