精细陶瓷(先进陶瓷,先进技术陶瓷). 大气压力下高温下陶瓷复合材料的机械性能. 面内剪切强度的测定

[中文适用范围]： 本文件规定了在空气或惰性气氛中高温下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 是钢筋的较大部分，方向 2 垂直于方向 1。 试件制造、测试模式和速率（载荷或位移速率）的方法，数据收集和报告程序得到解决。 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 < x ≤ 3）。 本文件用于材料开发、材料比较、质量保证、表征、可靠性和设计数据生成。 [外文原描述]： 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 ( x D, with 2 < x ≤ 3). This document is for material development, material comparison, quality assurance, characterization, reliability and design data generation.
