Optical 3D surface measuring system

• Subject Area: Materials Engineering
• Term: Funded in 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 460284478

The interdisciplinary working group "Intelligent Composite Materials" at Trier University of Applied Sciences has created a broad knowledge base in this research field in recent years. Motivated by developments in environmental protection, the energy revolution and the miniaturisation of medical technology, its members from the fields of electrical engineering, materials science, optical metrology and mechanical engineering are investigating the manifold characteristics of composite materials. These include natural fiber composites, laminated metallic implant electrodes and electrical cables used in energy and data transmission. Composite materials become "intelligent" by additionally integrating new functionality and serving as an interface to Industry 4.0.For their use in Industry 4.0, however, the composite materials must not only be intelligent, but above all they must be reliable. This is the challenge the working group is tackling: Recently published multiphysical research results of the working group could for the first time prove a correlation between the surface roughness of an electrical conductor and its remaining lifetime. Based on these results, the working group is currently developing a method in interdisciplinary cooperation to make the remaining service life of conductors measurable in-situ.In its research, the working group has reached a point where high-precision measurements of complex surfaces are absolutely necessary in the various fields of application. This can only be achieved by the requested Optical 3D Surface Measurement System.
