Abstract:The traditional ultrasonic B scan and C scan detection are unable to fully show overall perspective of
composite defects in composites. In this paper, the specimen with an artificial prefabricated flaw was detected by im鄄
mersion ultrasonic C scan imaging through the experimental method . Based on the principle of ultrasonic C scan the
bottom wave amplitude imaging, through one scan , ultrasonic reflected signals were acquired in different depth posi鄄
tion to form slice C scan imaging and slice C scan images were used for observe defects inside the material. Experi鄄
mental results have shown that, complex defects in composite materials can be multi angle imaging and full range of
clearly displayed by combined ultrasonic A, B, C scan imaging method with slice C scan imaging method.
