Research project:


Numerical optimization and automated production of load introductions in sandwich components

Research area: CAx, fiber 3D printing, lightweight construction, networked production
Supported by: Federal Ministry for Economic Affairs and Climate Protection
In collaboration with: 3D ICOM GmbH & Co. KG

Institute for Product Development and Construction Technology (TUHH)

Start of the project: September 2020  
End of the project: December 2023  


When producing lightweight components in aircraft cabins, a variety of lightweight construction-specific joining materials, so-called inserts, are used to introduce forces, connect components and connect them to the fuselage structure. Since the cabin is a unique selling point of the airline, 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 connection. Due to the open honeycomb structure in the sandwich composite, additional media such as adhesive, core filling compound 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.

The IFPT looks at approaches to automating connection points that are critical in terms of quantity and also examines the production of individual, load path-optimized connection points. Among other things, the aim is to investigate the extent to which existing connecting elements can be replaced by fiber-reinforced 3D printed components.
