Advanced composite materials have been used mainly for the secondary structures of the aircraft before the advent of B787 (Boeing Co. USA), a civil aircraft. In B787 aircraft, the composite materials are used for primary structures such as fuselage and main wings as well as the secondary structures such as rudders, elevators and other control surfaces. It was intended to save about 20% in weight by using composite materials which comprise more than 50% of the total structural weight, and is expected to improve the performance and efficiency of the aircraft. In this study, the advantages and disadvantages of the composite aircraft have been discussed and two R&D topics are selected and suggestions are made regarding the requirements for solutions of the future technical problems which are common to most of the composite aircraft. The two topics are : the enhancement of electrical conductivity of the carbon fiber reinforced composite, and the development of a real-time, online, automatic structural health and usage monitoring system for the aircraft applications.
