The instrument enables high-quality investigations of various materials and compounds. These include, for example, the structural analysis of fibre composites, the analysis of pore structures and distributions in metallic or matrix-bound materials, or the time- and location-dependent crack formation or delamination of adhered structures as a result of mechanical or thermal stress. The geometric structures of materials can be analysed via high resolution imaging data, which can be transferred into simulation models using automatic image data processing methods. Furthermore, damage processes and others can be detected non-destructively and with great accuracy while still in development.

The instrument enables high-quality investigations of various materials and compounds. These include, for example, the structural analysis of fibre composites, the analysis of pore structures and distributions in metallic or matrix-bound materials, or the time- and location-dependent crack formation or delamination of adhered structures as a result of mechanical or thermal stress. The geometric structures of materials can be analysed via high resolution imaging data, which can be transferred into simulation models using automatic image data processing methods. Furthermore, damage processes and others can be detected non-destructively and with great accuracy while still in development.
