In combination of the Nondestructive Testing (NDT) requirements,composite materials and their technologies are introduced.The working principle of Ultrasound Infrared Thermography is analyzed as well as its characteristics.The NDT experiments have been performed for the composite material specimens and the experimental results have been analyzed and evaluated,which have shown that this NDT method can effectively identify the defects in composite material specimens,especially the closed defects.
