With an airframe comprised of 50% carbon fiber reinforced plastic and other composites, the 787 entered history as the Boeing commercial airplane with the most extensive use of composite materials.The 777X wing will be 20% larger than the current 777 and made from composite, a super strong and lightweight material made from carbon fiber and resin.The Boeing 787 aircraft is 80% composite by volume. By weight, the material contents is 50% composite, 20% aluminum, 15% titanium, 10% steel, and 5% other [11]. Aluminum is used for the wing and tail leading edges; titanium is used mainly on engines and fasteners, with steel used in various areas.
What is the body material of the 787?
It’s Plastic (sort of) The Dreamliner is made of 50% composite materials, carbon fiber-reinforced polymers that are both lighter and more durable than traditional aluminum. Composite materials have been used before in passenger planes but never to this extent. They comprise both the wings and the fuselage of the 787. Half the weight of a 787 Dreamliner is made from lightweight carbon composite fiber. This material contributes significantly to the airplane’s superior fuel efficiency. The 2015 ecoDemonstrator program dismantled a 757 to learn more about airplane recycling.With an airframe comprised of 50% carbon fiber reinforced plastic and other composites, the 787 entered history as the Boeing commercial airplane with the most extensive use of composite materials.The Dreamliner is made of 50% composite materials, carbon fiber-reinforced polymers that are both lighter and more durable than traditional aluminum. Composite materials have been used before in passenger planes but never to this extent. They comprise both the wings and the fuselage of the 787.Under FAA oversight, we have painstakingly inspected and reworked airplanes and improved production quality to meet exacting standards. We are fully confident in the safety and durability of the 787 Dreamliner.The Boeing 787 Dreamliner’s wings curve during flight due to their flexibility, which is a result of the carbon fiber material used in their construction. This material allows the wings to stretch more than traditional wings made from metal.
What are the components of the 787?
The Boeing 787 Dreamliner is a long-haul, widebody, twin-engine jetliner, designed with lightweight structures that are 80% composite by volume; Boeing lists its materials by weight as 50% composite, 20% aluminum, 15% titanium, 10% steel, and 5% other materials. The order includes 130 fuel-efficient 787 Dreamliners and 30 777-9 jets. Additionally, the airline can acquire up to 50 more 787 and 777X airplanes.Boeing South Carolina is the home of the 787 Dreamliner, where the full cycle of Dreamliner production happens – from freezer to flight. Our teammates fabricate, assemble and deliver the 787-8, 787-9, and 787-10 to customers all over the world.The Boeing 787 Dreamliner has earned a strong safety reputation since its introduction in 2011. With more than 1,100 aircraft in service and over a billion passengers flown, it has maintained an exceptional record—experiencing no fatal crashes until June 2025.Boeing South Carolina is the home of the 787 Dreamliner, where the full cycle of Dreamliner production happens – from freezer to flight. Our teammates fabricate, assemble and deliver the 787-8, 787-9, and 787-10 to customers all over the world.In July, Boeing produced seven 787s, exceeding its current target of approximately four to five aircraft per month. This follows the production of six aircraft in June. The company has stated its intention to raise 787 output to seven aircraft per month by the end of the year and to ten per month by 2026.
Why did the 787 crash?
Seconds after take-off, both fuel-control switches on the 12-year-old Boeing 787 abruptly moved to cut-off, cutting fuel to the engines and causing total power loss – a step normally done only after landing. Just seconds after take-off, both of the 12-year-old Boeing 787 Dreamliner’s fuel-control switches abruptly moved to the cut-off position, starving the engines of fuel and triggering total power loss. Switching to cut-off is a move typically done only after landing.Seconds after take-off, both fuel-control switches on the 12-year-old Boeing 787 abruptly moved to cut-off, cutting fuel to the engines and causing total power loss – a step normally done only after landing.A total of 260 people were killed when the Boeing 787 Dreamliner crashed shortly after it took off from Ahmedabad last month. Indian investigators determined the jet was properly configured and lifted off normally. But three seconds after takeoff, the engines’ fuel switches were cut off.
What is the hull material of the Boeing 787?
The 787—a. Dreamliner—is the first commercial airplane in the world built largely from polymer composites. It’s a milestone in the use of plastic, an all-in wager for Boeing and a source of pride for composites experts at the University of Washington. The Air India incident on June 12 2025 – involving an 11-year-old aircraft – is the first time the 787 Dreamliner has crashed.Boeing 787 Dreamliner The 787 maintained a flight record of no fatal accidents since it was introduced. It uses modern composite materials and uses advanced avionics. It’s held the title of one of the safest commercial aircraft available.Boeing has begun final assembly of the 787-10 Dreamliner, the latest and biggest member in the Boeing 787 family of commercial aircraft. Two major fuselage sections for the aircraft have been moved to North Charleston, S. C.How many Dreamliners have crashed? The Air India incident on June 12 2025 – involving an 11-year-old aircraft – is the first time the 787 Dreamliner has crashed.The Dreamliner is a successful aircraft, still in production with more than 1600 delivered or on order. The list price for a new Boeing 787-8 is $239 million dollars.
What makes the 787 so special?
Advanced Aerodynamics: The Boeing 787 features advanced aerodynamic design, including raked wingtips and a smoother fuselage. These design elements reduce drag and improve fuel efficiency, allowing the aircraft to achieve a longer range. The 787 was built around composite wings, light, strong but incredibly flexible. So Boeing gave it an active system called Manoeuvre Load alleviation. In turbulence, the flight computer subtly moves the ailerons and spoilers to reduce structural stress instantly.The Sleek Boeing 787 Dreamliner The 787 is Boeing’s modern masterpiece, prioritizing fuel efficiency and passenger comfort. It’s smaller and lighter than the 747 but packed with advanced technology and a futuristic design.The Boeing 787 Dreamliner’s wing flex The Dreamliner’s wing design represents a shift in aviation engineering. Unlike traditional aluminum wings, the 787’s wings are made from advanced carbon fiber-reinforced polymer (CFRP) composites.
