Composites on the 787 will account for 50 percent of the aircraft's structural weight. Aluminum, by contrast, will comprise only 12 percent of the aircraft. In fact, titanium will make up a greater percentage than aluminum, at 15 percent. Steel will comprise another 10 percent and other metals, the remaining 5 percent.
