The revolutionary Boeing 787 Dreamliner, the first ever aircraft to be made of 50% carbon fibre composite material, make its international debut yesterday (Sunday 18th July) at the Farnborough Airshow.

An increased use of carbon fibre composite materials over traditional aluminium has significantly reduced the weight of the aircraft and there is a reported 20% saving in fuel with no compromise on speed. As well as this, the carbon fibre composite fuselage requires far fewer parts compared with aluminium as there is less to bolt together. A one piece composite fuselage section saves a total 1,500 aluminium sheets and 40,000 aluminium fasteners.
