Description

In an effort to develop and evaluate new non-destructive evaluation (NDE) techniques for resin-matrix composites, we have investigated the feasibility of utilizing electromagnetic imaging for materials evaluation and has demonstrated the ability of existing electromagnetic imaging techniques to detect and locate flaws within carbon-epoxy samples. This paper presents the technical issues associated with using electromagnetic imaging for NDE measurements. These include the selection of test frequencies, sample orientation, signal processing techniques, and the impact of material properties on the measurement results. Measured results are presented for carbon-epoxy material samples.
