Suivi de cuisson de composites Carbone/Epoxy par impédancemétrie électrique
Résumé
This article concerns the electrical characterization of T700/M21 unidirectional composite materials during the cure and the first step of a more global study aiming at the complete monitoring of the curing cycle using the material itself. It proposes a reliable and reproducible protocol for the characterization of the material during curing. The material is here used a sensor but could be also used as an actuator (functionalization) and the instrumentation will stay in the heart of the structure for SHM purpose. The present paper exposes the study of the correlation between measurements obtained by electrical and rheological techniques according to a specific curing cycle.
