The Fraunhofer Institute for Material and Beam Technology IWS has achieved decisive progress towards new ecological aircraft construction concepts. Within the EU programm Clean Sky 2 in the project “Multifunctional Fuselage Demonstrator” (MFFD), a team of researchers in Dresden provided proof of concept for the chipless joining of carbon fiber-reinforced thermoplastic component structures. The automated process approach developed joined the upper and lower halves of the world's largest CFRTP aircraft fuselage segment. In addition to saving on labor, for instance when drilling and riveting, the novel construction method and the CONTIjoin process enable massive reduction in weight, material and time. As a result, the production of future commercial aircraft should become faster, more eco-friendly and competitive. The researchers will present their results and the system technology at the International Aerospace Exhibition ILA 2024 in Berlin.
