TU/ecomotive, an Eindhoven University of Technology team focused on developing innovative, electric city cars, has unveiled its latest concept.
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.

The Institute for Advanced Composites Manufacturing Innovation (IACMI) has announced the Phase I completion of a project led by DuPont, partnering with Fibrtec and Purdue University, focused on the creation of a new carbon fibre composite manufacturing process that exhibits improved fabric formability characteristics compared to traditional woven materials.
Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
At SAMPE 2018 in Long Beach, Technical Fibre Products (TFP) will exhibit its advanced nonwovens, including the Tecnofire fire protection range, nano-coated materials and coated materials and Optiveil lightweight veils which aid surface finish and composite fabrication.
