DLR has built a large aircraft component out of CFRP as part of the EU Smart Intelligent Airframe Structures (SARISTU) project. Structural Health Monitoring (SHM) with Lamb waves is a promising technique for continuously testing fibre composite structures for damage during operation.

Layer by layer: the individual layers in a fibre metal laminate

Funded within the framework of the German Aviation Research Programme (LuFo), the ProfiRumpf project by the German Federal Ministry for Economic Affairs and Energy (BMWi) has, for the first time, succeeded in the production of double-curved fuselage segments from aluminium fibreglass laminate in assured quality using coordinated robot technology.

During the winter, aircraft suffer in the biting cold. As is the case with cars, ice can form on aircraft flight deck windows and flight instrument sensors. The wings are also among the critical points of aircraft, and icing can lead to significant aerodynamic penalties. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has found a solution to this issue. A new electric de-icing technology using carbon fibres melts the ice efficiently and can even prevent its formation. The functionality and energy efficiency of the innovative heating system were investigated using the de-icing test bed at the Technischen Universität Braunschweig (TU BS).

The DLR Institute of Composite Structures and Adaptive Systems has the know-how for the design and realisation of adaptable, efficient composite structures and lightweight systems. The DLR Institute forms the bridge between basic research and industrial application. With its expertise in multifunctional materials, structural mechanics, functional lightweight construction, fibre composite technology, adaptronics and composite process technology, the institute is oriented along the entire supply chain for the manufacture of flexible, efficiently manufactured and tolerant lightweight structures. With its wide range of services and visionary scientists, the Institute is a trusted partner of industry, academic institutions, the German Research Foundation (Deutsche Forschungsgemeinschaft; DFG), research institutions, ministries and regulatory authorities.
