The objective of this study was to investigate different defects and material systems (notch or delamination under carbon and boron composite patching bonded with FM73 adhesive film to the surface of Al 2024-T3) using several thermal non-destructive testing and evaluation techniques. Active thermographic approaches, using, firstly, a simple heat excitation source with an infrared camera, secondly, an integrated pulsed thermographic system, thirdly, pulsed phase thermography and lastly, thermal modelling, were used in the inspection of the composite aircraft repaired panels. In all situations the subsurface defects, were positioned intentionally. After the detection of the defects, representative images obtained from the thermographic investigation underwent quantitative analysis with the intention of obtaining information about the defects in space and in time.
