Characterizing complex metal-CFRP-hybrid structures by thermography
Abstract
In this paper results of non-destructive testing of metal-CFRP-hybrid structures are shown. The hybrid samples vary from 2D to 3D geometry. As NDT-method active thermography with its excitation modes flash and induction through an eddy current coil are used. It is shown that artificial induced defects like pleats in the CFRP-layer and mechanically induced delaminations at the interface CFRP/thermoplastic can be detected. For the latter defect, a different damage behavior can be shown depending on the geometry.
