Polarisation et charge d'espace dans une résine époxy par mesure Electro Acoustique Pulsée
Résumé
The "Pulsed Electro Acoustic" technique, which allows probing the space and time dependence of charge density within insulators, has been applied to probe polarisation and space charge phenomena within an epoxy resin. The response is analysed taking account the polarization phenomenon linked to the dipolar nature of epoxy resins. We show notably that it is possible to analyze the polarization through the space charge observation along time. Besides, current measurements are analysed and seem to confirm our interpretations
