Paper Abstract

An experimental investigation was conducted for the determination of defects at aircraft components and for the composite patches evaluation. Cracked aluminum panels, untreated and repaired with carbon and boron composite patches, were inspected. The non-destructive techniques used in the assessment of these aircraft materials were infrared thermography and fiber optics microscopy. Infrared thermography is used for the localization of defects on aluminum panels, as well as on repaired ones with composite patches. Furthermore, the detection of defects on repaired aluminum panels that have undergone to fatigue testing, is attempted. Fiber optics microscopy is employed in order to examine the surface morphology of both carbon and boron composite patches. The results of this laboratory research work can lead to the development of an integrated non- destructive method for in field inspections of aircraft components.
