Fribourg, Switzerland. Swiss sustainable lightweighting specialist Bcomp supplies its natural fibre composite solutions for all nine Spark Odyssey all-electric SUVs competing in the inaugural season of the Extreme E Championship. Starting in Saudi Arabia for the Desert X Prix, the state-of-the-art Spark Odyssey 21 off-road racing SUVs will compete clad with Bcomp’s sustainable lightweighting solutions in place of conventional carbon fibre.

 

Pushing the natural properties of flax fibre to the limit, Bcomp’s innovative ampliTex™ and powerRibs™ technologies are bringing a new dimension to sustainability in motorsport. The natural fibre bodyworks designed by Spark Racing Technology will be put to the test across five brutal race weekends spanning four continents.


The Extreme E Championship is an FIA-sanctioned international off-road racing series that seeks to highlight the impact of climate change while promoting sustainability and the adoption of electric vehicles. As such, Spark – the manufacturer of the race-spec Odyssey SUV – focussed on bringing together frontier electric vehicle technologies and industry-leading sustainability experts.

Théophile Gouzin, Technical Director of Spark Racing Technology said: “Bcomp’s natural fibre technologies are a perfect match for the goals we set for ourselves in Extreme E, achieving the highest level of sustainable performance and safety. We are very happy about the successful collaboration with Bcomp as both companies are technology leaders in sustainable motorsports.”

Bcomp’s proprietary powerRibs™ reinforcement grid uses the high specific bending stiffness of flax to boost natural fibre performance to the level of carbon fibre while offering an 85% cradle-to-gate CO2 reduction. In combination with the state-of-art ampliTex™ fabrics, Bcomp’s solutions enable sustainable bodyworks with the same stiffness and weight as carbon fibre while improving safety and damping. Natural fibre bodyworks minimise the risk of injuries of drivers, marshals, and spectators thanks to a ductile breaking behaviour, which, in case of an impact, results in pieces with blunt edges instead of producing sharp and dangerous debris like carbon fibre. Additionally, the 250% better damping properties improve driver comfort by lowering vibrations and noise levels, reducing fatigue over the course of a race.

 

While Bcomp’s award-winning technologies are already used in 16 racing series around the world, the applications are not restricted to motorsport. From automotive interior panels for electric performance brand Polestar, to luxury yachting and the European Space Agency’s latest natural-fibre satellite panels, Bcomp’s technologies are relied upon wherever weight, stiffness and sustainability are important.

Christian Fischer, CEO and Co-Founder at Bcomp, commented: “We are thrilled to be working with Spark to provide our sustainable lightweighting solutions for the Odyssey bodywork. Having our technology involved in this series is an incredible opportunity for Bcomp; racing in such a wide variety of locations, climates and terrains will really test our materials and conclusively demonstrate their capability and performance. Sustainable composites offer a practical path forward for so many industries, motorsport included. Given the volume of production, consumption, waste and emissions involved in the supply, use and disposal of carbon fibre, the implementation of sustainable composites is a clear step in the right direction.


Spark has managed to deliver a vehicle that is not only ready for the incredibly tough conditions of Extreme E, but also one that lives up to Extreme E’s ethos and ambition. It has been an incredibly exciting project to take part in and we can’t wait to see our natural fibre composites speeding across the desert on the first race weekend.”

McLaren Racing’s Sustainability Report

McLaren Racing recently released their Sustainability Report for 2021 and Bcomp is very pleased to be mentioned on several occasions throughout the report. Our partnership with McLaren has allowed us to have a positive impact in different areas. Race Logistics The work we did with McLaren Racing on the timing stand and engineers' island helped them to reduce travelling freight weight by 3450 kg. The new timing stand and engineers' island are made in a hybrid flax-carbon construction with Bcomp's ampliTex™ high-performance reinforcements making up the majority share. Replacing the previous carbon fibre components with natural flax fibre composites allowed McLaren Racing to decrease their amount of air freight and reduced their GHG footprint. Circular Design Our natural fibre technologies create high-performance alternatives to plastics and carbon fibre that come with viable end-of-life solutions. This allows McLaren Racing to explore new paths in circular design while they also keep working on alternative end-of-life solutions. A Successful Collaboration "Our partnership with Bcomp has been a game-changer in helping us find new opportunities for incorporating natural fibre composites into our design and engineering," states the McLaren Racing Sustainability Report. Together we have developed Formulas 1's first natural fibre racing seat. Lando Norris' new seat uses an optimised layup of ampliTex™ and powerRibs™ flax fibre solutions to replace the conventional carbon fibre layup. The pioneering natural fibre technologies reduce reliance on carbon fibre and single use plastic and lower the CO2 emissions by 85% compared to the seat's carbon fibre counterpart. We are excited to see what the future holds and how we can further advance sustainable lightweighting solutions from natural fibres in the course of this successful collaboration.

World-Class Craftsman Harnesses Natural Fibre Composites

The REI chair is a testament to the incredible build, surface and finish quality that can be achieved by using Bcomp’s ampliTex™ technical fabrics. Learn about how Tras Ltd., a Japanese composite company with a background in motorsport, has made its signature high-end designer chair far more sustainable. A World-Class Composite Craftsman From endurance motorcycle racing to luxury designer furniture, design and manufacturing studio Tras is a Japanese leader in composites. It is the latest organization to fly the flag of the Japanese composites industry – a craft that has been central to the culture for more than a millennium. Specialising in the design and production of carbon composites and other advanced composite materials (ACM), Tras began when its founder, Masanao Nitta, started to design bespoke carbon bodywork for race cars and motorcycles in 1988. In 2002, when established teams hesitated at his offer to provide bodywork, he decided to take action himself and started his own team to design and produce aerodynamic bodywork for the Suzuka 8 Hours, leading to a class victory with a BMW Motorrad in 2006. This eventually led to Tras being a partner for Suzuki’s Moto GP team from 2009, leveraging the deal through branding and exposure and further work within motorsport as Team Partner for the Toyota Motorsport GmbH's VLN bid with the LEXUS IS F CCS-R. Paying Homage to an Ancient Composite Tradition It was 2009 and Masanao Nitta had a strong desire to develop unique furniture that showcased his incredible carbon composite craftsmanship in an interesting way. Project REI was a collaboration between Tras and renowned Japanese designer Keita Shimizu. The team drew from Japan’s rich history of composite work, citing and paying homage to the 1,300-year-old Ashura statue. Made entirely from composites – flax fibres and urushi lacquer (a natural resin) – the statue depicts a god, stands around 1.5 metres tall and is considered to be a national treasure. When Masanao Nitta used carbon fibre composites in the first REI chair design, he went through countless steps of lacquering and surface polishing. Applying this ancient technique to today’s state-of-the-art composite materials, allowed Tras to achieve a unique tint that reflects the deep golden-brown of natural urushi lacquer. With the statue a well-known cultural icon of Japan, the chair paying homage to it quickly garnered attention. It was even exhibited internationally, including in Switzerland during Art Basel at the VOLTA fair. Showcasing Visual Perfection with ampliTex™ Drawing significant international attention to Japan’s rich history of composites and the expert application of carbon composites in furniture design and production, Masanao Nitta learned about the latest sustainable high-performance natural fibre composites. It was not long before he was in discussions with the Bcomp team about using ampliTex™ to produce a new version of the REI chair that closely mirrored the Ashura statue’s original flax fibre and urushi lacquer construction. The new, natural fibre REI highlights the level of quality and craftsmanship that is possible with industry-leading flax fibre composite reinforcements. The unique aesthetic of ampliTex™ was perfectly suited to this high-end design application with the flax weave entirely visible across the ‘bowl’ shaped structure of the chair. With visual perfection and quality paramount to ensuring the chair meets the expectations of discerning customers, ampliTex™ was the ideal choice thanks to its unique high-end appearance. A Perfect Match for Furniture and Luxury Goods With advanced composites becoming an increasingly popular material within high-end furniture design and production, the use of natural fibres that cannot only match the visual quality of carbon but add their very own unique appearance, could be an important step towards decarbonising the industry. To learn more about the use of Bcomp’s ampliTex™ and powerRibs™ technologies in furniture and luxury goods, please get in touch with our design team.

Bcomp is Official Partner of the Foiling Week SuMoth Challenge 2022

Bcomp is very proud to be official partner of the SuMoth challenge that took place this weekend on beautiful Lake Garda during the Foiling Week. Sunny skies, perfect wind conditions and a great atmosphere made for an amazing event. The SuMoth Challenge The SuMoth challenge invites student teams from all over the world to design, build, and eventually race a sustainable foiling Moth. The teams bring together students from different backgrounds to work on a common goal and gain valuable experience with sustainable technologies driving the future of sustainable boat building. Teams have to go through all the phases from material selection and design process, to engineering, actually building the Moth and finally getting it on the water. Time and budget constraints add to the complexity of this endeavour. Such a project can only be tackled with the right support and the teams can count on the partners of the SuMoth challenge. Sharing Knowledge Bcomp has a long tradition of passing on its knowledge and expertise in natural fibre composite solutions to students who will shape the future of many an industry. Needless to say, we were more than happy to support teams during the challenge. Paolo Dassi, Bcomp’s Marine and Industry Manager, held a masterclass on biobased composites for the participating teams. These masterclasses allow the students to benefit from the concentrated knowledge of the SuMoth partners and to gain valuable insights. Talking to the teams on location and hearing first-hand how the masterclass has helped them and given them inspiration for new ideas, was simply great. Many of the teams on site mentioned that they are actively exploring the use of natural fibres for anything from updated and improved components to entire new hulls for next year’s event. Finally Taking Flight We saw incredible commitment and effort from all the teams over the course of the Foiling Week. They all had their own setbacks and victories, working tirelessly to get their innovative and sustainable Moth to take off, and to make a point for their design and material choices. Especially standing out, were moments such as the Moth from Canadian team Rafale ETS taking flight for the first time ever, or the entire PoliMi Sailing Team working tirelessly late into the evenings to finally take home a shared first place in the design stage and 2nd place in stage 2, just to name a few. We congratulate all the teams on their great boat designs and are already looking forward to seeing more teams and boats with natural fibre components by next year. Foiling Week The Foiling Week was a great success with a lot of interesting racing action, many initiatives to help people achieve their first foiling experience and cool side events such as the Foiling Film Festival. There was also a row of panel discussions on all the topics around foiling spread out over the long weekend. Bcomp was represented by Paolo Dassi, its Marine and Industry Manager, who could contribute his expertise during the discussion about Building Sustainability into Foiling. The entire forum sessions were streamed live and are now available on YouTube. https://www.youtube.com/watch?v=gJ-F_iSrens Learn more: SuMoth Challenge The Foiling Week All images © Bcomp / Flurin Efinger Have a question or want to stay in touch?
