Abstract:

Extensive use of composite materials is a prominent characteristic of airframe design for the new generation large commercial aircraft. The amount of composite materials has reached up to 50% of the airframe weight. Composite structures not only significantly decrease the structural weight, but also improve the performance of corrosion resistance, fatigue and maintenance. Boeing 787’s humanity design of the entire composite fuselage significantly improved passenger comfort and convenience.
