Enhancing Circularity in Aerospace Manufacturing: The National Composites Centre's New Initiative
Pioneering advancements in composite recycling to significantly reduce waste in aerospace production
07.06.2024
The National Composites Centre (NCC), in collaboration with Munich-based Cevotec, showcases a sustainable solution for aerospace manufacturing waste, aiming to reclaim up to 80% of dry fibre material. This proof-of-concept could revolutionize waste management practices by utilizing innovative Fibre Patch Placement technology.
Economic Significance and Background
The aerospace sector, pivotal to the UK's economy, faces stringent demands for lighter, faster-produced aviation systems while adhering to net zero targets. Traditional waste disposal methods such as landfilling are increasingly untenable due to rising costs and environmental impacts.
Addressing Recycling Challenges in Aerospace
In aerospace manufacturing, significant material waste occurs during the ply cutting phase, where up to half of the virgin materials are discarded. The NCC's initiative focuses on recycling these materials to maintain their value and utility in the manufacturing chain.
Introducing Technology for Innovative Recycling
Cevotec's Fibre Patch Placement (FPP) technology plays a crucial role here. By cutting carbon dry fibre waste into specific patches, this technology ensures efficient use of materials. The NCC team employs automated ply cutters to create precise patches needed for effective FPP application. Florian Lenz, Technical Director for Cevotec, emphasizes the adaptability and efficiency of this method: "Fibre Patch Placement technology offers a new option for flexible and productive composite manufacturing, generating value from material scrap."

Showcasing Results and Environmental Benefits
- Material Reclamation: Initial tests show a potential to reclaim nearly 40% more virgin materials, thus reducing waste significantly.
- Economic Impact: Utilizing waste as FPP feedstock could save approximately £912,000 annually from a single aerospace component by reducing landfill deposits.
Expanding Impact and Planning for Future Developments
Looking ahead, the use of FPP technology is expected to extend beyond single components, potentially incorporating more of the aircraft build and thus amplifying environmental and financial benefits. The integration of digital technologies could further optimize the manufacturing process and material usage. Tim Young, Head of Sustainability at the National Composites Centre, outlines the broader vision: "To achieve net zero, we need to invest in new ways to reduce and remove carbon emissions from how we consume it: from concept, design, and manufacture to end-of-life recycling and disposal."
Exploring Future Developments in Sustainable Manufacturing
The NCC plans to refine the FPP technology for more complex components and collaborate with industry partners to test these innovations in real-world settings. This will include a broader evaluation of sustainability and economic impacts associated with dry fibre manufacturing waste.
