چکیده

Detection of multi-layer composite material using F-scan ultrasonic imaging system was studied. Layered defects could be identified with focused transducers, and testing results could be displayed by various imaging modes (C、phase feature and CT). Density and thickness of composite material could be measured with the system.

Research of Double Mode Ultrasonic Testing in Multi-layered Adhesive Structure of the Solid Rocket Motor

In inspecting steel-rubber multi-layered structure, shielding of steel layer and intense attenuation of rubber layer result in ultrasonic echo from the interfaces of the deep layers being very weak. In order to overcome the difficulty, the double mode testing method is put forward. This method synthesizes the characteristics of transverse wave and Lamb wave testing. In the double modetesting tr...
