The longer the rotor blade, the greater the amount of adhesive required to bond the two blade shells together. Rotor blade manufacturers currently require around one tonne of adhesive for a rotor blade that is around 80 metres long, resulting in high costs. The scientists at Fraunhofer IWES have therefore utilised their experience from a decade of research into the manufacture of rotor blades and developed a solution that simplifies and improves the adhesive application process: the Variable Glue Applicator (VGA).

The greatest potential of digitalization in companies in which materials play a prominent role lies in the cross-process linking of materials data. This promises to shorten component development times, faster optimization of complex manufacturing processes and more reliable plant operation. The problem is the very heterogeneous nature of materials data, which makes linking within this data extremely complex. The research project MaterialDigital of the state of Baden-Württemberg under the leadership of the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg has now made great progress in structuring materials data into a continuous data space.
