Structural health monitoring of a smart composite structure with a Time-of-Flight method

Résumé

Smart composite structures with a fully distributed set of integrated piezoelectric transducers are used to demonstrate the feasibility of embedded Structural health monitoring (SHM). Indeed, the piezo ceramics elements have been directly integrated into the heart of the composite during the manufacturing process. Then, a Time-of-Flight method has been applied. This technique is based on the duration measurements of a wave propagation with a simple and low cost experimental setup. Integrated piezoelectric transducers are used for monitoring the behavior of the structure. In this research, special plates (with a piezo ceramics disk on each corner), made of glass fibre composite, are manufactured. Different kinds of damages are simulated on these plates, including holes with different diameters. Then a Time-of-Flight method is used for the SHM of these plates. Finally, the preliminary test results obtained on one plate are compared and discussed.
