Wir brauchen eine neue Haut! Flugzeugrumpf aus Faser-Metall-Laminat

Abstract

The use of fiber-aluminum laminates allows substantial advantages over a fuselage skin made of monolithic aluminum materials due to the low fatigue, the high load tolerance and the resistance to residual stress. This material has already been used in the wide body aircraft of the Airbus Group A380 on the upper fuselage shells. However, this is not enough: due to the further development of the used materials and the construction methods, very thin FML with a 50 per cent lower skin thickness will be able to be realized in the future compared to the state of the art in the Airbus A380. In addition to the above-mentioned advantages, this also results in a weight reduction and makes this material interesting for next generation aircrafts. A new process chain for the automated fuselage shell manufacturing of these thin FML components is the focus of DLR's research work, especially with respect to scale 1:1.
