Flying longer and burning less fuel requires dropping some weight from already lean, high-flying fighting machines. Government and private-sector researchers have been working to replace hefty metals such as titanium with lighter composite materials for decades. Their goal is to boost performance and to lessen environmental, health, and safety concerns.

To replace titanium in aircraft, the Air Force and commercial aerospace manufacturers such as Boeing, General Electric, and Europe’s Airbus have turned to advanced composite . . .
