Description

The detection of disbonds in a laminated structure is the focus of many nondestructive techniques.One of the promising techniques is thermography, where heat is applied to a structure, and the subsequent temperature profiles are detected with an infrared (IR) imager.If there is an even application of heat, an elevated temperature profile will appear, as a result of the reduction in heat flow from the surface layer to subsurface layers.Two advantages of the thermographic technique over more conventional ultrasonic techniques are that it can be easily made noncontacting and that large areas can be inspected in a short period of time.
