Ceramic matrix composites have been widely used in the field of aeronautics and astronautics because of its excellent properties such as highlighted mechanical properties at high temperature

low density and good oxidation resistance performance. Using nondestructive testing methods to make testing on ceramic matrix composites has significant meanings in ensuring the quality of materials and improving the reliability of related products. In this paper the current state and development of the nondestructive testing of the ceramic matrix composites are summarized. Principles of terahertz

Xray

industrial CT

infrared thermal imaging

ultrasonic wave and acoustic emission for the ceramic matrix composites are elucidated in detail

and their applications in ceramic matrix composites are introduced.
