BioMobile to incorporate bio reinforcements in automotive body frame

News International-French

19 Mar 2012 is a prototype that minimizes CO2 emissions, in both its construction and its use. was originally developed as an energy-efficient vehicle intended for international competitions such as the Shell Eco-Marathon, whose goal is to cover the most kilometres with one litre of fuel. Over the years, the prototype has been continuously improved to integrate the most innovative breakthroughs in terms of bio-based fuels and materials.

The production and use of fossil fuels raise environmental concerns. A global movement toward the generation of renewable energy is therefore under way to help meet increasing energy needs. For this purpose, developed X41, a biofuel made from organic waste. Unlike almost all other biofuels, which are substitutes for fossil fuel, X41 is an equivalent, both physically and chemically. Therefore, it can be used in any engine without modifying the existing technology and without sacrificing performances. To demonstrate this, is powered by a brushcutter engine and its fuel consumption is close to 0.10 litres per 100 km. project draws on the resources and expertise of hepia’s teaching staff and students (haute école du paysage, d'ingénierie et d'architecture de Genève – University of Applied Sciences of Western Switzerland) as well as the collaborations with several establishments and companies. It provides opportunities to develop and test technologies that could be used in other applications with the same objectives.



Showcased at this year’s JEC Composites show in Paris, the will exhibit a brand new body frame made of bio-composites. The upper part is reinforced with banana fibres for the aesthetical aspect, whereas the lower part, whose shape is more complex, is made of Greenlite® reinforcements from PORCHER Industries. In both cases, the resin used for the production of the body parts is derived from pine wood. This development was realized in partnership with id-composite and Maquette 74.



Greenlite® is a new generation of renewable woven fabrics developed by Porcher Industries. These materials are based on pure cellulose fibres, which is the most abundant and renewable biomass on earth. Greenlite® materials are biodegradable and highly compatible with bio-based resins, making them suitable for the production of 100% bio-based composites on a large scale. Greenlite® reinforcements constitute a significant advance in terms of sustainability, strength and quality, overcoming the typical limitations encountered when using natural fibres in industrial bio-composite applications.


The uses a significant amount of “green” materials. The next stage consists in completing the substitution by renewable products in the remaining structural components.
