摘要	To estimate the disbond defects of the glass fiber composite materials applied in the solid rocket motor, active infrared thermographic NDT is researched. Firstly, the numerical analysis of the transient thermal wave distubance under the pulse heating stimulation is carried out using the finite element method. Then, the special experiment is arranged. The specimen including 3 disbond defects with diameter 10mm, 20mm and 30mm is pulse heated using 2 symmetric pulse heating sources, which the stimulation time is 2ms and the pulse energy is 4800J. The surface transient temperature is monitored by the infrared camera system. Finally, The experimental results are compared with the ultrasonic C-scan. Our research shows that the infrared thermography is a fast and effective inspection method for detecting defects of the diameter over 10mm and depth within 5mm in the composite materials
