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.
