本文件规定了一种在空气或惰性气氛中通过双刃缺口试样的不对称四点弯曲试验测定连续纤维增强陶瓷复合材料在高温下的面内剪切强度的方法。可以评估平面（1，2）中的剪切强度，其中方向1是钢筋的大部分，方向2垂直于方向1。讨论了试件制造方法、测试模式和速率（载荷或位移速率）、数据收集和报告程序。本文件适用于所有具有连续纤维增强的陶瓷基复合材料:单向（1D）、双向（2D）和三向（xD，其中2

This document specifies a method for the determination of in-plane shear strength of continuous fibre-reinforced ceramic composites at elevated temperature in air or inert atmosphere by the asymmetric four-point bending test on double-edge notched specimens. The shear strength in plane (1,2) can be evaluated, where direction 1 is that of the greater fraction of reinforcement and direction 2 is perpendicular to direction 1. Methods for test piece fabrication, testing modes and rates (load or displacement rate), data collection and reporting procedures are addressed.This document applies to all ceramic matrix composites with continuous fibre-reinforcement: unidirectional (1D), bidirectional (2D) and tridirectional (xD, with 2 < x ≤ 3).This document is for material development, material comparison, quality assurance, characterization, reliability and design data generation.
