Abstract: Aiming at the problem of detecting the defects of the corner of the carbon fiber composite square bar, the difficulty of detecting the corner of the composite bar is analyzed. The sound field distribution of the common linear array transducer probe was simulated and analyzed. The CIVA software was used to optimize the simulation process of the carbon fiber square rod. The comparative test block with natural defects was tested and verified. The ultrasonic phase control was proposed. Based on the detection scheme of the array detection method, the test results show that the method of line sweep and fan sweep using the line array transducer can effectively solve the defect detection problem of the corner of carbon fiber composite rods.

Key words: ultrasonic phased array, nondestructive testing, composite rods, corner
