Infrared thermography (IRT) is increasingly used to detect defects in composites. However, IRT of composites faces more challenges due to their complex structure compared to that of monolithic-materials. In this article, the authors built model to perform IRT simulations of several types of defects found in composites. Subsequently IRT experiments were performed to verify simulation results. And then, Ultrasound C-scan, micro-CT and Terahertz NDT are preformed to conduct a comparative study of different NDT techniques. Finally, a comparison of the detection capabilities of different NDT techniques was conducted through matching and fusing of the results of experiments and simulations.
