les avions du futur seront construits en graphène

Sir Richard Branson has raised the prospect of planes being made entirely from the so-called wonder material graphene within 10 years, as the airline industry battles a 50pc increase in fuel in the last 12 months, sparking a desperate need for ever lighter fleets.
"Hopefully graphene can be the planes of the future, if you go 10 years down the line. They would be massively lighter than the current planes, which again would make a difference on fuel burn."
