The bonnet and roof of the Tesla-based Electric GT World Series racing car, as featured at this year’s JEC World in Paris, incorporate the powerRibs technology of Swiss-headquartered Bcomp.
Marrying the properties of flax fibres with a new preform design, the ptechnology allows weight savings of up to 40% in single skin composite shell applications to be achieved, with a reduction in both material cost and environmental footprint, the company says.
Bcomp introduced two composite preform kits at the Paris show – powerRibs F01 and C01, a full flax and hybrid carbon-flax laminate developed in collaboration with the European Space Agency, ESA, respectively.
Both allow stiff and lightweight solutions for automotive race body parts to be achieved. Available in either prepreg form or dry fabrics for infusion processing, Bcomp’s fabrics are easy to use and do not require resin-hungry bleeders or flow media for processing. Customers can either choose to reduce weight of their benchmark carbon or carbon/glass laminates by up to 40%, or reach higher stiffness for the same part’s weight.
Structural damping is also significantly due to the high vibration absorption properties of the natural fibre.
