【Abstract】 The quality control and assurance of ceramic matrix composites by non-destructive testing(NDT) have always been a challenge due to their anisotropy,inhomogeneity,and urgency of application in aeronautic and astronautic fields.In this paper the current state and development of the non-destructive testing of the ceramic matrix composites are summerized.Principles of three significant NDT methods:Ultrasonic wave,infrared thermal imaging and industrial X-ray CT for the ceramic matrix composites are introduced in detail,and their application progress for ceramic matrix composites is elucidated.更多还原
