标准范围

本文件规定了通过双缺口试件的压缩测定环境温度下的层间剪切强度的方法和通过Iosipescu试验测定环境温度下的层间剪切强度和模量的方法。本文件适用于所有具有连续纤维增强的陶瓷基复合材料，具有单向（1D）、双向（2D）和多向（xD，其中x？>？2）纤维结构，其中增强物的主要部分是层的堆叠。本文件适用于材料开发、材料比较、质量保证、表征、可靠性和设计数据生成。只有当必须测量剪切强度时，双缺口试件的更简单的压缩测试方法才适用。

This document specifies a method for the determination of interlaminar shear strength at ambient temperature by the compression of a double-notched test piece and a method for the determination of interlaminar shear strength and modulus at ambient temperature by the Iosipescu test. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, having unidirectional (1D), bidirectional (2D) and multidirectional (xD, with x > 2) fibre architecture, where a major part of reinforcements is a stack of plies.

This document is applicable to material development, material comparison, quality assurance, characterization, reliability and design data generation. The simpler compression test method of a double-notched test piece is applicable only when the shear strength has to be measured.
