高温下陶瓷复合材料的机械性能.压缩性能的测定

[中文适用范围]： 本文件规定了在空气、真空和惰性气体环境中测定增强陶瓷基复合材料的压缩行为的程序。 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）和多方向（xD，其中 \(x>2\)），这些材料沿着增强纤维的主要轴线或偏离轴线条件下的 2D 和 xD 材料均适用。 本文件还适用于碳纤维增强碳基体复合材料（也称为碳/碳或 C/C）。 [外文原描述]： This document specifies procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at elevated temperature in air, vacuum and inert gas atmospheres. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bidirectional (2D) and multi-directional ( x D, with x > 2), tested along one principal axis of reinforcement or off axis conditions for 2D and x D materials. This document also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C). Two cases of testing are distinguished: compression between platens and compression using grips.
