STUNNING | World’s largest known thermoplastic aircraft structure

Introduction to the STUNNING Cleansky2 project

An 8.5 meter long fuselage skin made of thermoplastics has been produced by automated fibre placement. Within the MFFD framework Royal NLR, together with GKN Fokker (lead), TU Delft, and Germany’s Diehl, have taken on their own project called STUNNING. Their goal is to demonstrate and validate how the use of composites, namely thermoplastics, can help realize a next-gen fleet of aircraft capable of offering the same strength and durability of steel and aluminum, while drastically reducing the total time of production and maintenance activities, as well as the overall weight of aircraft and the subsequent emissions.

JEC Group is a non-profit organization entirely dedicated to promoting composite materials and fostering their applications globally. Publisher of the JEC Composites Magazine, the industry's reference magazine, JEC organizes several events around the world, including JEC World, the leading international exhibition dedicated to composites and their applications, which takes place annually in Paris. JEC media, events and digital channels connect a global community of professionals from the composites industry and beyond, to enable knowledge transfer, create networking opportunities, and highlight innovation.
