Numerische Optimierung und automatisierte Fertigung von Lasteinleitungen in Sandwichbauteilen

In the production of lightweight components in aircraft cabins, a large number of lightweight-specific joining materials, so-called inserts, are used to transfer forces, connect components and join them to the fuselage structure. Since the cabin is a unique selling point of the airlines, the components have a highly individual product design. Not only the number and type of inserts varies, but also their position and the type of joint. Due to the open honeycomb structure in the sandwich composite, additional media such as adhesive, core filler or metal plates are necessary to create suitable joints. The aim of the project is to create a holistic development and production process for the simulative design and digital production of load introduction points. <pclass="text-justify">The IFPT is looking at approaches to automating connection points that are critical to the number of units and is also investigating the production of individual, load-path-optimised connection points. Among other things, it will be investigated to what extent previous connection elements can be substituted by fibre-reinforced 3D-printed components.
