Lightweight Construction

Set founded in many industries, such as about the aerospace and the automotive, Fraunhofer spin-off SURAGUS GmbH in Dresden more and more lightweight, because by the weight of the vehicle fuel consumption and pollutant emissions significantly reduce. In this context, the increasing use of carbon-fibre-reinforced plastics (CFRP), which are similar to robust despite the lower weight such as conventional materials is available. The increased use of carbon fibre requires providing adequate testing for the detection of material damage in these composites. The start up SURAGUS was established with participation of the Fraunhofer-Gesellschaft develops customer-specific solutions based on Eddy current technology in this area. In addition to the testing of CFRP is the Eddy current method for the quality control of layers of transparent conductive oxide (TCO) and many other thin functional coatings. The demands on quality and on the safety of industrial products rising and with them also the Demand for material testing. Always accurate and it efficiently and easily practicable test methods are needed. The Fraunhofer Institute for non-destructive testing IZFP is working on developing such test solutions, belongs to among other things also the Eddy current technology. The Eddy current method particularly suitable for assessing quality of fibre and composites, functional coatings, TCO layers, joints or raw materials, such as Silicon purity testing. MJFF wanted to know more. Beginning of 2011 researchers of the Fraunhofer IZFP founded the SURAGUS GmbH to commercialize this testing technology based on Leifahigkeitsunterschieden. The Fraunhofer-Gesellschaft is involved in the start-up of Frafer venture. The technology: Eddy current process defects, structural variations and changes of material properties cause in many cases a local change of conductivity. This can be based on the Eddy current testing technology developed at the Fraunhofer IZFP detect themselves. The Eddy current method uses local conductivity variations for the characterization of quality attributes such as thickness, layer resistance, material uniformity or other physical changes in the inspection of goods.
