Paper Abstract

We describe the application of IR thermal wave imaging for the nondestructive evaluation of composites and coatings. The technique uses pulsed surface heating and fast, synchronous IR imaging of the surface temperature to form images of subsurface defects in materials. In the case of composites and coatings, we present examples of the detection of defects such as delaminations, disbonds, subsurface impact damage, fluid infiltration, etc. The technique can be used to measure the depths of defects, and also the thicknesses of various coatings.
