Multimodal and in-situ characterization of inhomogenous materials

MiCi: 01/2016 - 12/2021

Multimodal and non-destructive testing (NDT) methods are essential in order to characterize materials during their processing, e.g. during thermo-mechanical treatments, and to enable in-situ monitoring of the production process. In this project different NDT methods will be realized in a multimodal test rig. This enables the comparability of different NDT methods. In addition, a new high-resolution X-ray computed tomography system with in-situ stages will be acquired and used for the characterization and validation of NDT methods. Beneath experimental validations, resolution limits of the different NDT methods will be compared to theoretical limits. The experimental and theoretical approach will help to identify the best NDT methods for characterizing certain processes and to locate critical defects within the inspected materials.

The aim of this project is to characterize inhomogeneous materials by a multimodal (simultaneous use of different NDT methods) and in-situ (during a running process within the material). Especially the “microscopic” characterization of inhomogenous materals during in-situ monitoring is of importance, such as microstructural changes in metals, changes of inner stresses in plastics or the quality of adhesion of joints or glued surfaces. The approaches within this project are beyond state-of-the-art, since common used NDT-methods are usually targeting only “macroscopic” properties such as wall thickness or defects in final parts (e.g. cracks, pores or shrinkage cavity). The multimodal aspect covers more material properties at once. The comparability between different NDT methods will be used to critical discuss advantages and disadvantages for certain inspection tasks. The project should strengthen the growth and claim the top position in terms of technology in the fields of material industry (metals, plastics, sandwich materials) as well as the automotive and aeronautic industry in terms of a better product quality and production efficiency. Further areas such as food industry and medical technology will be also targeted.
