Abstract:

To realize fast visual detection of carbon fiber composite materials, the principle of laser ultrasound visual detection system is studied. Using a scan laser mode, the laser ultrasound visual detection system has advantages of simple structure and easy operation. It is designed based on the reversibility principle of ultrasound propagation, and can be used in fast and visual detection of carbon fiber composite materials. Experiments are carried out. The results show that the system can effectively be used to detect defects in carbon fiber composite materials. It has high accuracy and fast detection speed, only a few microseconds for each detection task. The detection results are straightforward and can display internal defects of the structure dynamically in real-time. The information of ultrasound transmission can be replayed and selected according to time frames. The system can be used to determine the location and sizes of defects. With the visual detection system, it is easy to achieve full non-contact detection. It is suitable for on-line real-time monitoring of structures made of carbon fiber composite materials.
