JEC Composites Innovation Awards: Finalists in Aerospace Process Category

The 2024 edition of the JEC Composites Innovation Awards has kicked off with the naming of three finalists per category. The awards ceremony will take place in Paris on Feb. 8, 2024. Here we profile the successful entries in the Aerospace Process category.

Aspera welded thermoplastic composite demonstrator

Company: Spirit AeroSystems (USA)

Partners: A&P Technology (USA), Concordia Fibers (USA), Electroimpact (USA), Mitsubishi Chemical Advanced Materials (USA), NIAR (USA), Victrex (USA)

Description: In preparation for future aerospace challenges, Spirit AeroSystems has fabricated details utilizing automated fiber placement, stamp forming, and novel pressure intensification processes. Welding is done with the patented Co-Fusion and induction processes, demonstrating fastener-free high-rate manufacturing. Aspera is representative of a large portion of a typical commercial aircraft cabin but is made entirely from thermoplastic composite details welded together.

Fastener-free assembly methods are adopted to minimize weight and cost while utilizing rapid fabrication processes that enable future high-rate single-aisle commercial aircraft production. Both patented and proprietary novel fabrication and welding processes are used to make the part. These processes were developed internally by Spirit AeroSystems and represent state-of-the-art thermoplastic composite technologies and tooling methodologies.

One-shot in situ consolidation wing upper cover

Company: Airbus DS – Defence & Space (Spain)

Partner: FIDAMC (Spain)

Description: One-step in situ consolidation of polyetheretherketone (PEEK) thermoplastic resin based carbon-fiber composite was used to fabricate a transport aircraft external wing skin cover, which is part of the primary structure, through an ecofriendly process. This approach enables low energy consumption processing and end-of-life recycling.

Thermoplastic resin based composites are a key enabler toward sustainability of composite structures in aerospace due to their recyclability and performance. Airbus Defence and Space (engineering) and FIDAMC (manufacturing) have produced a thermoplastic in-situ consolidated (ISC) upper cover for airframe under the ITD CleanSky2 platform for integration into an outer external wing box specimen. This is the first demonstrator of a primary structure using ISC with integrated stringers and without a post-consolidation step. An exhaustive testing campaign substantiated technology readiness level (TRL) 5, including mechanical characterization, detail, subcomponent level, and full scale up to ultimate load.
