    Fuses, modules and interconnect cables are widely used in many different technical environments – applications range from inside conventional control cabinets to space. While the automation degree in fabricating various technical components is increasing, wiring remains a laborious and error-prone manual process. Researchers at Fraunhofer IWS, together with partners such as AIRBUS, are developing processes to manufacture conductive paths in a cost-efficient and safe manner.

    Many people associate steel construction technology with manual welding and glaring arcs. In order to manufacture large-scale, highly stressed steel structures such as overhead cranes or wind turbine towers in line with high quality standards, exten¬sive technical expertise and efficient processes are required. High-energy, modern joining processes such as laser beam welding will revolutionize steel construction in the coming years. A research project conducted over the past 2.5 years on low-distortion and low-energy laser beam welding for thick-walled steel structures follows precisely this goal.

    Already in the early stages of component development, standardized characteristic values are indispensable for the selection of materials. However, as development advances, focus shifts to application-oriented load scenarios. At Fraunhofer IWS, these scenarios can be transformed into individual test procedures by directly linking process knowledge and material understanding.

    The new material class of high-entropy alloys (HEA) promises many innovations in aviation, turbine and tool construction as well as other industries. Testing the countless variations in the chemical composition of this material class would require research and development lasting thousands of years. Researchers at Fraunhofer IWS have further enhanced methods for material design that will enormously accelerate this work.

    Bonds against electrostatic discharges

    News – Fraunhofer IWS Dresden / May 20, 2021

    Flexible electrically conductive adhesive and potting systems modified by carbon nanotubes enable electrostatic charges to be dissipated (ESDBond) and at the same time protect against electromagnetic interference (carBONDshield).

    In the "ESDBond" project, the Kunststoff-Zentrum (SKZ) and Fraunhofer IWS successfully modified flexible electrically conductive adhesives and potting compounds to dissipate electrostatic charges. In this process, they achieved significant reductions in electrical volume resistance by adding smallest amounts of carbon nanotubes (CNTs). Based on these results, the follow-up project "carBONDshield" is investigating possibilities for using such modified systems for electromagnetic shielding.

    Today, new coatings on brake discs meet increasingly complex requirements. Conventionally, a destructive metallographic cross-section is used to check their quality. This method is expensive, slow and resource-intensive. Fraunhofer IWS researchers have now demonstrated that a fast and non-destructive evaluation can also be achieved using the LAwave® method.
