The piezoelectric implant method: implementation and practical applications

Résumé

Previous laboratory-developed studies have validated an original method enabling the in situ real-time health monitoring of a composite structure by means of an inserted piezoelectric sensor. In order to extend such a method from laboratory conditions to the industrial situation, it is necessary to take the two kinds of defects linked to the non-correct positioning and to the imperfect bonding of the piezoelectric plate in the structure to be characterized into account. We have proposed a specific criterion to detect and evaluate these types of imperfection by using analytical relations linking acoustical parameters extracted by the numerical method. The applications have concerned the in situ monitoring of the curing and the local damage assessment of a polymer-based composite.
