Abstract
In composite structures, some of the most critical areas susceptible to damage are inaccessible due to assembly or manufacturing procedures. In order to scan or monitor the structural integrity on those zones, a multidisciplinary approach that involves smart materials, additive manufacture, embedded systems, and wireless communications among others is proposed. Thus, a piezoelectric transducer array is deposited or placed around the region of interest and used to interrogate, on-ground or in-flight, the state of the composite structure. Then, Lamb-wave tomography and acousto-ultrasonic techniques are used to identify and localize any damage.
