标准摘要
[中文适用范围]: 本国际标准描述了一个程序——使用均匀加载拉伸或压缩的参考测试样本来验证试验机负载序列的不对中程度,以及——给出指示以纠正诸如扭转和弯曲之类的缺陷。 本国际标准无意在测试带有纤维增强材料的陶瓷基复合材料之前提供定量和可接受的限值:单向(1D)、双向(2D)和三向(xD,其中 2 < x ≤ 3)沿一个方向加载强化主轴。 该限制取决于每种类型的复合材料对未对准缺陷的敏感性。 注 1:该限值由测试机构和客户共同定义。 注 2:整体陶瓷对不对中缺陷非常敏感,而 CMC(陶瓷基复合材料)一般对不对中缺陷较为敏感。 [外文原描述]: ISO 17161:2014 describes a procedure to verify the degree of misalignment of the load train of the test machines using a reference test specimen uniformly loaded in tension or in compression, and to give indications in order to correct defects such as torsion and bending. ISO 17161:2014 is not intended to provide a quantitative and acceptable limit before the testing of ceramic matrix composites with a fibre reinforcement: unidirectional (1D), bidirectional (2D), and tridirectional ( x D, with 2 < x ≤ 3) loaded along one principal axis of reinforcement. This limit depends on the sensitivity of each type of composite to the misalignment defect.
