Description

technical field [0001] The invention belongs to the technical field of mechanical processing of fiber-reinforced composite materials, and in particular relates to a detection device for the hole quality of finished composite materials. Background technique [0002] The detection of drilling defects in composite materials is of great significance. On the one hand, it can evaluate the quality of hole processing, and on the other hand, it has guiding significance for the drilling process. [0003] At present, the detection methods of composite material damage include infrared detection, microwave detection, X-ray detection, eddy current detection, ultrasonic detection and so on. In the prior art, ultrasonic testing has the characteristics of accurate defect location and wide application range, and is widely used in damage detection and quality assessment of composite materials. For example, the patent CN112730454A adopts ultrasonic wave and infrared wave fusion detection. How...
