The German Aerospace Center (DLR) has achieved a significant milestone in the NATURE programme with the world's first Automated Fibre Placement (AFP) laminates manufactured using ultra-thin CF-LMPAEK prepreg plies.
Developed by Fukuvi Chemical Industry Co., Ltd., the material measures just 45 μm per ply, containing as few as seven fibres in the vertical direction — nearly one-third the thickness of standard CF-LMPAEK.
This leap in material architecture unlocks three times the fibre-orientation flexibility, enabling highly optimised layups for next-generation aerospace and space structures. Early trials have delivered excellent consolidation quality, validating the material's suitability for lightweight, high-performance thermoplastic composite structures.
Funded by the German Federal Ministry for Economic Affairs and Energy, NATURE targets low-emission helicopter structures and brings together Airbus Helicopters, Fraunhofer IGCV, and TU Dresden. More performance data and application insights are expected as the programme advances.
Making the next generation of composite structures for space and aviation lighter and more efficient requires re-thinking not only the structure, but also the material itself. The team recently completed a major milestone in the project NATURE, using Automated Fibre Placement (AFP) to manufacture laminates from very thin plies of CF-LMPAEK with excellent results.
The project NATURE is funded by the German Federal Ministry for Economic Affairs and Energy. The project focuses on the production of new lightweight helicopter structures for lower emission aviation and includes partners such as Airbus Helicopters, Fraunhofer IGCV, and Technische Universität Dresden.
