Boeing and Oracle Team USA, winners of the 34th America’s Cup, are collaborating to recycle over 3 tonnes of carbon fibre from the USA-71, a yacht built for the America’s Cup campaign in 2003.
The hull and mast of the racing yacht will be processed and repurposed, a first-of-its-kind effort for what will likely be the largest carbon structure ever recycled.
Boeing and the Oracle team, working with research partners, will utilise a technique developed to recycle composite materials from Boeing’s 787 Dreamliner, which is 50 percent composite by weight and 20 percent more fuel-efficient than similarly sized aircraft. Composite materials allow a lighter, simpler structure, which increases efficiency, and do not fatigue or corrode. In yachts, composite construction also provides the ability to develop a lighter vessel that is stronger and stiffer at the same time.
Chris Sitzenstock, ORACLE TEAM USA logistics said;
The introduction of composites in yacht construction was a major step in our sport. The materials and processes have continued to evolve, allowing us to build the high-tech, high-speed AC72 catamarans raced in this year’s America’s Cup, now we have the ability to work with Boeing to take the next steps in composite recycling, and to help reduce our environmental footprint. We will also look to recycle carbon components remaining from the build of our yachts.
Boeing and Oracle Team USA will work with the University of Nottingham in the United Kingdom and MIT-RCF, a South Carolina company specialising in repurposing carbon fibre components. In 2006 Boeing began collaborating with the University of Nottingham on carbon fibre recycling and they continue to work on recycling processes and technology to process the recycled fibre into new applications.
USA-71’s hull will be cut into 4-foot sections and the mast will be chopped into manageable pieces before it is processed; about 75 percent of the recycled composites will come from the hull and the remaining 25 percent from the mast.
Boeing and Oracle Team USA expect to gather data about the mechanical properties, costs and time flows to recycle sailing-grade composite materials in comparison to aerospace-grade and automobile-grade composites. Although the companies have not determined the post-recycling use of the yacht’s carbon fibre, potential end uses include consumer and industrial products.[rssless]
