| Abstract: | F-scan ultrasonic imaging testing technology was introduced.An F-scan ultrasonic imaging auto-testing system for multi-layer composite materials was developed successfully.The feature parameters of defects could be extracted accurately with the system.The results could be displayed by various imaging modes(B,C,F and phase feature imaging).Defects could be identified by setting proper decision conditions.The ultrasonic computerized tomography was studied.Detailed appraisal of agglutination between layers and density of composite materials can be seen directly from the imaging. |
