This paper summarizes the nondestructive testing and evaluation （NDT＆E） for CFRP laminate with subsurface defects using an infrared thermal wave imaging （TWI） including the principles and approaches, thermal wave signal processing algorithms, defect determination and detection, probability of detection （POD） of defect using TWI and defect size and depth identification. The application and advantages of TWI for NDT＆E of composites are expressed, and the applicability and limitation of TWI are deeply discussed. Additionally, special emphasis is focused on the practical application of TWI on the CFRP laminate with subsurface defects, and some trends in the further development of TWI for CFRP laminate NDT＆E are described.
