Abstract

An electromagnetic method allowing to localize and characterize main damages inside composites such as CFRP and GFRP, has been developed. This method is based on the local measurement of the induced electric field, by electric excitation (GFRP) or magnetic induction (CFRP). All damages inducing a local variation of electric conductivity and/or dielectric permittivity, one can detect and characterize damages inside composites materials by analysis of these two parameters. On the other hand, this technique allows detecting some damages having non mechanical origin such as liquid ingress (e.g. water oil, fuel...) or small burns generated by electric sparks (e.g. short circuits, lightning impacts), these kinds of damages being quasi non detectable by more classical methods such as ultrasonic analysis.
