In Situ Nondestructive Evaluation of the Accumulative Damage in Continuous Ceramic Fiber‐Ceramic Matrix Composites (CFCCs) using Submillimeter Range Electromagnetic Wave

Monolithic ceramic materials usually show catastrophic failure behavior and this property limits application as structural components because the failure occurs easily from a small flaw that usually exists in the materials. To overcome this, incorporation of a fine ceramic fiber into a brittle ceramic has been examined and the obtained material is named as continuous fiber‐ceramic matrix composites (CFCCs).
