Abstract
A new concept of Structural Health Monitoring System for composite materials, (CFRP and GFRP) using electromagnetic properties of the material, has been developed at ONERA (Office National d’Etudes et de Recherches Aerospatiales, France). This concept, based on the detection of local electric conductivity variations and/or local dielectric permittivity variations, has allowed to design a demonstrator having a great sensitivity to detect main defects such as delaminations, fiber breaking, burning and liquid ingress. However, this technique at the present state, does not presently allow to perform quantitative measurements of electric conductivity and dielectric permittivity. In order to remedy to this disadvantage, a numerical simulation with an original method developed at ENS-Cachan (Ecole Normale Superieure de Cachan, France) by D. Placko and N. Liebeaux, has been performed. Various results obtained by simulation are presented discussed and compared with experimental measurements.
