At the same time, airlines are eager to improve operating costs and reduce the impact of maintenance expenses through higher payloads and more fuel-efficient aircraft. Airlines are also under increasing pressure to replace their aging fleets with more fuel-efficient and quieter aircraft to become more environmentally friendly. As a result,

The Boeing 767, one of the first commercial aircraft to make extensive use of composites , entered service in 1983 and 6% , consisting primarily of internal secondary composite structures. Boeing's legacy 777, which entered service in 1995, has approximately 11% . 

The Airbus A380 was first delivered in 2007, with a tail structure made of composites, with 23% . The Boeing 777X has been redesigned with composite wings and composite-intensive engines, with a composite content of more than 30% . The Boeing 787 officially entered service in 2011, with a carbon fiber 50% . The Airbus A350 XWB ("A350") was first delivered in December 2014, with a composite content of 53% .

. 

As air travel recovers and demand for the latest generation of fuel-efficient aircraft increases, Airbus and Boeing will begin to increase the production rates of existing aircraft platforms in 2022; and as commercial aviation productivity increases, it can be predicted that the demand for carbon fiber composites will further increase steadily.
