The vehicle, named Lina, employs a combination of bio-based composites and bioplastics to create a lightweight chassis. The bio-based composite is based on flax, and has a strength to weight ratio similar to that of glass fibre.
A honeycomb core made of PLA (polylactic acid) – a 100% biodegradable resin derived from sugar beets – is placed between two flax fibre composite sheets to produce a sandwich panel offering high stiffness and strength at minimal weight. EconCore’s technology for cost-effective, continuous production of thermoplastic honeycomb materials was used to manufacture the honeycomb based on PLA from NatureWorks.
According to TU/ecomotive this concept has the potential to drastically reduce carbon footprint compared to other lightweight materials used in the industry.
Lina’s power is supplied by modular battery packs, giving an output of 8 kW. The car has a top speed of 80 km/h. NFC technology implemented in the doors is used to detect and recognise different users, which makes Lina highly suited for car-sharing platforms.
Lina can be seen during the Shell Eco-Marathon 2017 on 25-28 May in London, UK and the car will tour The Netherlands from 5 June.
