Porsche Motorsport innovates with series production of bio-based composites

Porsche Motorsport demonstrates the possibilities of series production of natural fibre parts in motorsports and is nominated for a JEC Innovation Award in the Sustainability category. The project was realised together with associated partners Bcomp, Four Motors and the Fraunhofer-Anwendungszentrum HOFZET.

 

Showcasing innovation in motorsport bodywork 

The specific properties of natural fibres were used to allow the lightweight design of  sustainable doors and rear wing. Meeting all the technical requirements, parts made from ampliTex™ flax fabric and powerRibs™ flax reinforcement grid manage to tip the scales at the same weight as components made of carbon fibre reinforced plastic. Porsche Motorsport demonstrates the technology readiness in two completely different load cases with the door as a body part and the rear wing being dynamically loaded. 

 

Established production processes 

To manufacture these parts from natural fibres, the same manufacturing techniques were used as with standard carbon fibre parts. The doors make use of a Balsa wood core which allows them to achieve similar bending stiffness as comparable synthetic sandwich parts made with carbon fibre. The rear wing makes perfect use of Bcomp’s powerRibs™ technology to meet all the technical requirements with a minimal amount of fibres and was manufactured in an autoclave process, while the doors were made in a classic RTM (resin transfer moulding) process. 

 

Small series production 

This case from Porsche Motorsport shows how  it is perfectly possible to process natural fibres in large scale series-compatible processes. Seeing that the doors and rear wings are already produced for 700 vehicles, they can be clearly distinguished from prototype parts and manage to show the application potential of natural fibre reinforced plastics for road going sports cars and the future mobility market in general.

Extreme E embraces high-performance natural fibre composites

Sustainable lightweighting specialist Bcomp partners with Spark for all-electric race SUV Extreme E car features natural fibre bodywork using Bcomp’s ampliTex™ and powerRibs™ Bcomp’s solutions enable bodyworks with 85% less CO2 cradle-to-gate than carbon fibre Five-race Season 1 will see intense off-road action from the arctic to the amazon First event, Extreme E Desert X Prix, to take place in Saudi Arabia 3rd & 4th April Bcomp ampliTex™ + powerRibs™ natural fibre bodywork - © QEV Technologies 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.” Learn more: www.extreme-e.com www.sparkracingtechnology.com Previous Next
