Frontiers in materials for air frame structure

Airframe structures are combinations of high strength light weight materials. Selections of materials are considered from smaller army aircraft to larger civil transportation aircraft. Accident free constructions of aircraft structure produce economical transportation for passenger and cargo. High speed flights vary application of materials from civil transport Boeing 747 to concord. Studies of properties include mainly fatigue, fracture toughness, stiffness, strength, corrosion and thermal states effected properties, e.g., high speed flights which raise skin temperatures by air friction and turbulences.
