      • Abstract
    • Carbon fiber reinforced plate(CFRP) was widely used in aero industry for its high strength and low weight. CFRP plates with five different impact energies were inspected by pulse thermography. With transient or modulated temperature field applied on object sample, surface temperature variation was recorded by infrared camera. After acquisition, the data was processed according to corresponding heating type and the results were given as graphs. Ultrasonic C-scan was used as validation.
