Any damage in the fibers of these composites requires an evaluation in order to ensure the integrity of aircraft structures. Composite materials are subject to various degrees of damage during their service life and therefore maintenance of these light-weight structures is a new challenge for non-destructive testing (NDT) which requires techniques that respond with a high probability of detection of defects on such high-specific strength materials. In this thesis, Digital shearography and Infrared Thermography (IRT) techniques are employed to test aircraft composite materials.
