Paper Abstract

The extensive use of advanced composite materials on aircraft has increased the need for improved inspection techniques. Presently, graphite composite structures for high performance military aircraft require extensive ultrasonic and X-ray inspection for the detection of porosity, delaminations and disbonds. Thermographic inspection offers the potential for a lower cost alternative to these techniques. Much of the work on the application of thermographic techniques as an alternative to the above means of inspection has been qualitative and limited to laboratory use. The transient thermal response of graphite composite structures has been shown to be useful in detecting porosity, delamination and disbonds, and the use of image processing simplifies operator interpretation of the resulting data. This paper describes further research on this subject and proposes systems for production use and field inspection of advanced composite structures.
