He was quoted saying "hopefully graphene can be the planes of the future. 10 years down the line. They would be massively lighter than the current planes, which again would make a difference on fuel burn." Branson likened the push for graphene planes to urging Airbus and Boeing to make planes from carbon fibre, a battle he won. Boeing's latest 787 Dreamliner planes are made from 50% carbon fibre and other composite materials, as opposed to the traditional 100% aluminium. They use 30% less fuel than their standard alternatives.
In October 2016, Graphene 3D Lab developed a graphene-enabled composite with potential uses in the automotive and aerospace industries. In July 2016, Scientists at Manchester University were working towards developing a new graphene-coated aeroplane.
