Intelligent detection and evaluation of impact damage of typical aircraft structures

The low energy impact damage of typical carbon fiber reinforced composite structures was taken as a breakthrough point. According to the nondestructive testing requirement of defect evaluation, data set of aviation composite impact damage labelled by professionals was constructed. The research of an efficient artificial intelligent assistant inspection tool was conducted to enhance the data of ultrasonic images, train the target detection model of ultrasonic impact damages, and achieve intelligent detection and evaluation of impact damages.
