Which aircraft was the first to be made primarily of composite materials?

• A. Boeing 737
• B. Airbus A320
• C. Lockheed Martin F-22
• D. Boeing 787 Dreamliner

Answer: (D)

The Boeing 787 Dreamliner holds the distinction of being the first commercial aircraft made primarily of composite materials. This groundbreaking design utilizes a composite structure that constitutes approximately 50% of its airframe, including the wings, fuselage, and tail. The use of composites offers several advantages, such as reduced weight, increased fuel efficiency, and improved resistance to corrosion compared to traditional aluminum structures.

The decision to use composite materials significantly contributed to the 787's design goals of efficiency and performance, enabling it to achieve longer ranges and lower operating costs for airlines. The innovative use of these materials illustrated a shift in aerospace engineering, setting new standards for future aircraft designs that followed.
