Dielectric properties of various kinds of fiber-reinforced ceramic matrix composites have been measured and the measured dielectric properties are used as an indicator of damage stored in the composites. Experimental set-up, which consists of dielectric lens, horn antenna and high-frequency (20-40 GHz) network analyzer, is prepared for the purpose of damage detection. The set-up allows non-contact and non-damage measurement of the change in dielectric properties due to introduced microfracture events. The relationships between dielectric properties and damage parameter, and, damage parameter and applied tensile load, are obtained and used them as a master curve of the evaluation of stored damage. Through this relation stored unknown tensile damage of SiC fiber-reinforced SiC matrix composites is successfully determined. The procedure is also applied for the evaluation of oxidation damage in SiC fiber-reinforced SiC matrix composite. Similar to the mechanical damage, the change due to oxidation of SiC is clearly detected. Summarizing these set of results, the method is presented as a "non-contact", "non-destructive" detection procedure for ceramic fiber-reinforced ceramic matrix composites.

已经测量了各种纤维增强陶瓷基复合材料的介电性能，并且将测量的介电性能用作复合材料中存储的损坏的指标。实验装置由介质透镜、喇叭天线和高频（20-40 GHz）网络分析仪组成，用于损伤检测。该装置允许对由于微断裂事件导致的介电性能变化进行非接触式、无损伤的测量。获得介电性能与损伤参数、以及损伤参数与施加的拉伸负载之间的关系，并将其用作评估存储损伤的主曲线。通过该关系式，成功确定了 SiC 纤维增强 SiC 基复合材料存储的未知拉伸损伤。该程序也适用于评估 SiC 纤维增强 SiC 基复合材料的氧化损伤。与机械损伤类似，可以清楚地检测到 SiC 氧化引起的变化。总结这组结果，该方法被提出为陶瓷纤维增强陶瓷基复合材料的“非接触”、“非破坏性”检测程序。
