Study of Infrared Thermograph NDT of Airplane Composites

Abstract:

In this paper, infrared thermal wave NDT techniques are used for aircraft composites. After the infrared image is sharpened and the temperature field is analyzed, aircraft composite material defects can be diagnosed. Experiments show that the infrared NDT techniques can detect defects in aircraft composite image. Images and first-order differential image can be presented more clearly outline the process and temperature variations. Defect size and depth can also be measured. The best experiments are designed for different materials. After several experiments of the precise temperature calibration can be further studied. Defects can be interpreted intelligent.
