精细陶瓷（先进陶瓷 先进技术陶瓷） - 陶瓷复合材料的机械性能在空气中的环境温度大气压力 - 拉伸性能的测定

[中文适用范围]： 本文件规定了在室温下测定连续纤维增强陶瓷基复合材料拉伸性能（包括拉伸模量、泊松比、强度、最大力应变和断裂应变）的条件。本文件适用于所有连续纤维增强陶瓷基复合材料，包括单向（1D）、双向（2D）和多向（xD，x>2）增强，沿主增强轴加载。注：大多数情况下，在空气中高温使用的陶瓷基复合材料涂有抗氧化涂层。 [外文原描述]： This document specifies the conditions for determining the tensile properties (including tensile modulus, Poisson’s ratio, strength, strain at maximum force and fracture strain) of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, including unidirectional (1D), bi-directional (2D), and multi-directional (xD, with x > 2), reinforcement, loaded along a principal axis of reinforcement. NOTE In most cases, ceramic matrix composites to be used at high temperature in air are coated with an antioxidation coating.
