ENGEL Debuts Fully Automated Thermoplastic Composite Drone Rotor Blade Line
ENGEL introduced a fully automated production line for thermoplastic composite drone rotor blades at JEC World 2026 in Paris, starting March 3, 2026. The system integrates automated placement of carbon-fiber-reinforced thermoplastic tapes, injection of a short-fiber thermoplastic core, chemical foaming, and functional trimming in a continuous cycle-all executed on a tie-bar-less ENGEL victory 120 machine with an easix six-axis robot. The process delivers rotor blades in under 60 seconds per cycle1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL. This development supports scalable, high-quality composite manufacturing for drone applications, with potential for use in automotive and aerospace sectors.
Background
ENGEL has pursued integrated composite manufacturing with its Organomelt and Fluidmelt technologies, previously showcased at JEC World 2024 and 2025. These earlier demonstrations focused on lightweight, automated processes for aviation and automotive components2Engel auf der JEC World 2024: Thermoplastische Composite-Bauteile für die Automobilindustrie - Kunststoff Magazin. The 2026 demonstration advances this strategy by introducing full automation in tape-sandwich injection molding specifically for high-throughput rotor blade production.
Details
The process uses a sandwich construction: carbon-fiber-reinforced thermoplastic tapes form the load-bearing outer layers, positioned by vacuum fixation. A short-fiber thermoplastic compound is then injected to create the inner core, which is chemically foamed to reduce weight while maintaining structural integrity1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL. Noise-reducing features, such as serrated trailing edges, are incorporated through interchangeable mould inserts, minimizing acoustic emissions without secondary machining1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL. The fully automated system takes advantage of the ENGEL victory 120 machine's tie-bar-less design, allowing unrestricted robot access and sub-60-second cycle times1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL.
The NeoBlade research project supports the demonstration, drawing on expertise in aeroacoustics, tool and material development, process automation, and sustainability analysis. Project partners include ALPEX Technologies, JKU Linz's Energy Institute, FACC Operations, Plastic Innovation, and TU Wien's Aircraft Systems Research Group1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL. The consortium assessed high-temperature and cost-effective thermoplastic systems, including variants reinforced with recycled carbon fibers. Life-cycle assessments showed a significant reduction in CO₂ emissions compared with traditional thermoset processes, highlighting the recyclability benefits of thermoplastic composites1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL.
In addition to the rotor blade, ENGEL is displaying a 1.3 × 1.8 m high-voltage battery cover-a finalist for the JEC World Innovation Awards 2026-manufactured using the same tape-sandwich injection moulding process. The cover combines lightweight construction, stiffness, functional integration, and full recyclability1ENGEL at JEC World 2026: First fully automated series production of thermoplastic composite rotor blades for drones - ENGEL.
Outlook
ENGEL's demonstration at JEC World 2026 positions thermoplastic composite injection moulding as a viable, automated manufacturing method for both small-scale drone components and larger mobility sector parts. The NeoBlade project's results may contribute to further industrialisation of sustainable, high-throughput composite production in aerospace and automotive markets.
