摘要

With Airbus's giant A380 airliner about to take to the skies, you might think planes could not get much bigger-and you would be right. For a given design, it turns out, there comes a point where the wings become too heavy to generate enough lift to carry their own weight. But a new way of designing and making materials could get around that problem. Two engineers at University College London, Sia Mahdavi and Sean Hanna, have devised an innovative way to customise and control the properties of a material throughout its three-dimensional structure. In the case of a wing, this would make possible a material that is dense, strong and load-bearing at one end, close to the fuselage, while the extremities could be made less dense, lighter and more flexible. It is like making bespoke materials, says Mr Mahdavi, "because you can customise the physical properties of every cubic millimetre of a structure."
