Wissenschaftliche Nachwuchsgruppe

Das Fraunhofer WKI und das Institut für Baustoffe, Massivbau und Brandschutz (iBMB) der Technischen Universität Braunschweig bieten jungen Wissenschaftlerinnen und Wissenschaftlern die Möglichkeit, eine gemeinsame Arbeitsgruppe aufzubauen, um innovative Lösungen für die Gebäude der Zukunft zu entwickeln. Eine multidisziplinäre Nachwuchsgruppe untersucht derzeit das Langzeitverhalten und die Dauerhaftigkeit von Holz-Hybridsystemen für tragende Konstruktionen im Hochbau. Sie wird vom Bundesministerium für Ernährung und Landwirtschaft (BMEL) gefördert. Projektträger ist die Fachagentur für Nachwachsende Rohstoffe e. V. (FNR).
