标准摘要
[中文适用范围]： 本标准规定了连续纤维增强陶瓷基复合材料（包括碳纤维增强碳基复合材料）在空气、真空和惰性气体气氛中高温下恒定拉伸载荷下应力-断裂时间图的测定条件。 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），沿增强材料的一个主轴加载。 注1：在大多数情况下，在空气中高温下使用的陶瓷基复合材料都涂有抗氧化涂层。 注2：由于试验的主要目的是获得应力-断裂时间数据，因此变形测量不是强制性的。 [外文原描述]： ISO 19604:2018 specifies the conditions for determination of the stress-rupture time diagram of continuous fibre-reinforced ceramic matrix composites (including carbon fibre-reinforced carbon matrix composite) at high temperature in air, vacuum and inert gas atmospheres under constant tensile loading. ISO 19604:2018 applies to all ceramic matrix composites with continuous fibre reinforcement: unidirectional (1D), bidirectional (2D) and tridirectional (xD, with 2 < x ≤ 3), loaded along one principal axis of reinforcement. NOTE 1 In most cases, ceramic matrix composites to be used at high temperature in air are coated with an antioxidation coating. NOTE 2 Since the main purpose of the test is to obtain the stress-rupture time data, the deformation measurement is not mandatory.
