ISO 20504:2006描述了在室温下连续纤维增强的陶瓷基复合材料的压缩行为的测定方法。该方法适用于所有具有连续纤维增强，单向，双向和三向的陶瓷基体复合材料，沿着一个主轴线加固。该方法也可应用于碳纤维增强碳基复合材料（也称为碳/碳或C/C）。两种测试案例的区别是:使用夹具压缩压板和压缩

ISO 20504:2006 describes procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at room temperature. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional, bi-directional, and tri-directional, tested along one principal axis of reinforcement. This method may also be applied 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.
