Composite materials have been effective in weight reduction and are thus used for all structural applications and parts of both spacecraft and aircraft including fighter aircraft, space shuttle and passenger airliners. Since they have exclusive stiffness-to-density ratio and providing high amount weight reduction, composite materials are highly attractive for aviation and aerospace applications. Many new projects indicate that use of composites will increase in commercial aerostructures for coming decades.
For an example commercial aviation has increased the usage of composites to around 50% of total weight of the aircraft. Airbus A350 is built utilizing 52% CFRP, while Boeing 787 Dreamliner is built using 50% CFRP in terms of weight. Surge in commercial aviation is expected to drive the global CFRP market over the forecast period.
