Contribution to Conference
In this study, we present an online-monitoring approach using silver nanoparticle based ink on carbon fiber reinforced plastics (CFRP). After production of CFRP plates in a prepreg autoclave process and printing conducting paths on the material, we investigate the interface of CFRP and conducting paths of printed silver nanoparticle based ink by light microscopy. Mechanical tests with simultaneous electrical resistance measurement demonstrate the applicability of the presented method for a structural health-monitoring system. Delaminations can be detected and localized inside of the material by electrical through thickness measurements. Furthermore, resistance measurements of the conductive paths allow for surface crack detection and might be established as alternative method to other structural health-monitoring methods.
