CFRP，減重；裏麵有供應商鍋

The Boeing 787 Dreamliner is primarily constructed from composite materials, specifically carbon fiber-reinforced plastic (CFRP), making up about 50% of its weight. The fuselage, wings, and tail are built with these composites, offering a lighter and more durable structure than traditional aluminum. Other materials, including aluminum, titanium, and steel, also contribute to the 787's construction.
