Abstract: Ultrasonic phased array inspection for the corner of composite components was researched on experiment. The difficulties of the corner inspection and advantages of ultrasonic phased array inspection technique were dealt with. Then two kinds of inspection methods with curved array transducer and linear array transducer were put forward. The experiments of the corner inspection of L-shaped composite component were conducted with the two methods, which verified the correctness of the two kinds of methods. Finally, the two inspection methods and conventional ultrasonic inspection method were contrasted and the advantages of the corner inspection using ultrasonic phased array technique were summarized. The results show that ultrasonic phased array technique is a feasible, efficient detection method, which can satisfy the inspection requirement of the corner of composite components.
