Carbon fiber composite materials play an indispensable part in the weight reduction and performance improvement of fuselage.
Just like spacecraft, aircraft is another field where weight reduction is very important and use of carbon fiber began early. In the 1970s, carbon fiber was adopted for spoilers, elevators and other secondary structural materials and proven effective. In the late 1980's, carbon fiber found its way into primary structural materials such as tail plane and cabin beams. U.S.Boeing and E.U. Airbus, which are large aircraft manufacturers, have been increasing the amount of carbon fiber used per aircraft with every new model, and both the large-size Airbus A380 that began serving the sky in 2007, and the mid-size Boeing 787 premiered in 2009, use more than 30 tons of CFRP per aircraft. In particular, the Boeing 787 uses CFRP for around 50% of its structure weight, and the outer panels covering the main wings and body of this breakthrough aircraft are all made of carbon.
Carbon fiber composite materials are not used in engine parts that become hot, etc., but the engine's fan containment case, blades, etc., use carbon fiber and as the issues of fuel economy and CO2 emissions will likely become increasingly important, utilization of carbon fiber in other areas including engines should accelerated dramatically.
