New Approaches in Nondestructive Characterisation of Defects in Metal - CFRP Hybrids

Abstract:

In this paper a new metal - CFRP (Carbon Fibre Reinforced Polymer) hybrid concept is introduced. The new aspect of this hybrid is a thermoplastic polymer component inserted between the metal and CFRP structure to reduce the gap of the different stiffnesses in each structure. To characterise defects in the hybrid, both destructive and nondestructive testing (NDT) approaches are shown. Especially the interface between the metal structure and the thermoplastic polymer component as well as the interface between the thermoplastic polymer component and the CFRP structure, where is most-likely the starting point for cracks, are investigated. An additional probability of detection (POD) approach enables to connect fracture mechanics with crack values of NDT. In consequence it is possible to achieve the assessment of defect-caused damage progress, so called effects of defects.
