Abstract: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.
