The world’s first graphene bike – light, strong and aero. UK manufacturer Dassi uses graphene in the bike frame. They say:
” We mix graphene with an epoxy resin we developed ourselves that is then electronically functionalised to disperse the graphene evenly within the resin. The carbon weave is then introduced into the resin mix, which in turn forms the graphene carbon material in a prepreg that can be used for laying up components.
Unlike a standard carbon lay up, the working time with graphene is significantly reduced. Skilled engineers and refined processes are required to optimise the lay up of a graphene bike frame.”
“Dassi makes this vision a reality, with its new road bike frame crafted with this remarkable substance: graphene.
By combining the carbon allotrope with existing products and altering an epoxy resin originally used by the European Space Agency, Dassi has been able to create hyper-composites and harness the potential of graphene.
We can manufacture bicycles with frames that boast 70% more inter-laminar shear strength, meaning that you the rider can rely on outstanding build quality even in the most extreme conditions. And with 50% more fracture toughness, retarded crack propagation and increased carbon-to-resin adhesion all before we even think about the hyper conductivity and hydrophobic properties of graphene.
Weighing in at just 750g unpainted, with the same stiffness and strength characteristics of those standing at 950g.”
WHY DOES THE GRAPHENE FRAME ONLY CONTAIN 1% GRAPHENE?
With a sheet of graphene being only one atom thick, 1 gram of graphene could cover an area as big as a football pitch, so only a small percentage is required when building a frame to gain enormous advantages.
Just 1% graphene enables us to reduce the weight of our carbon frames by approximately 30%. Not only that – it also causes a gain in the frame stiffness. Incredibly impressive, but both are really just by-products of the main benefits, its hydrophobic properties and hyper-conductivity.”
