Paper Abstract

Bicycles, cars, airplanes, prosthetics, solar panels...composites are ubiquitous in the modern world. Three thermographic NDT techniques are currently in use for the detection and measurement of defects in these composites, including defects such as impact damage, delamination, voids, inclusions and stresses. The particular technique for optimum results, pulsed flash, pulsed transient, or lock-in, depends upon the sample material and thickness and shape, and the test environment. Choice of camera type varies widely, from high performance cooled to affordable uncooled, with large format 640 x 480 pixels now available, also. NDT hardware and software now includes models that allow all types of excitation sources and excitation methods with the same equipment.
