Abstract:

The present development and tendency of new materials used in large aircraft are introduced. The primary structural materials used for current American and European large airframes are undergoing a transition from aluminum alloys to advanced composites, and 50% of composites seems to be a starting point for future aircraft. The material technology for new generation large aircraft will be characterized primarily by the recordhigh application of composite materials and titanium alloys, in order to reduce the structural weight and fuel consumption significantly.
