Aircraft cabin partitions are commonly made in sandwich design consisting of a lightweight core and two cover layers of fibre-reinforced plastic composites. The critical points of these structures are the load introduction points. For this purpose, so-called inserts with a potting compound are integrated into the structure. For larger loads, hard fabric blocks are used. A suitable design for the load path is only possible to a limited extenn, so that overdimensioning is occurring.

The aim of the sub-project is to develop a mechanically and structurally optimised aircraft cabin partition, which is intended to be manufactured in one piece on the basis of the laser-based DED (Direct Energy Deposition) process in order to replace previous sandwich laminate constructions. The focus of the Institute of Product Development and Mechanical Engineering Design at TU Hamburg is on the design of this structure, taking into account the restrictions and safety factors caused by the manufacturing process. At the end of the project, a complete, large-scale demonstrator (size approx. 2000 x 1200 mm) should be manufactured.
