Paper Abstract

Carbon Fiber Reinforced Plated (CFRP) with Foam sandwich has the merits of high strength and light weight, which was used in the fields of manufacturing industry, aeronautics and astronautics. The basic principles and characteristics of the ultrasonic infrared thermography is discussed in the paper. The ultrasound is introduced into the sample, and the mechanical vibration weakens and transfers to heat at the place where defect or crack locates. A infrared camera monitors the surface temperature distribution and records this process. A CFRP foam sandwich structure sample with five pre-embedded defects was inspected with ultrasonic infrared thermography. The results is shown and compared with pulsed thermography.
