Detailed characterization of a CFRP lightning impacted specimen by complementary phase imaging techniques on synchrotron and in the laboratory

Résumé

Today, we use more and more carbon fiber reinforced polymers (CFRP) in the aerospace industry. When they are damaged by lightning, defects can be formed in their structures. To understand these defects, an approach is to couple laboratory controlled induced lighting with non-destructive evaluation (NDE). Many NDE methods are used to study CFRP [1], among which X-ray imaging allows volume inspection with high spatial resolution. However, low attenuation carbon materials bring low contrast on the image. To improve it, the contribution of the phase signal of the X-ray wave front modified by the sample is considered in addition to the attenuation signal.
