In recent years, with the gradual development of China's low-altitude airspace, the general aviation industry has developed rapidly. Carbon fiber composite materials have gained wide attention and application in the design and manufacture of general aircraft due to their advantages of low density, high specific strength and specific modulus, good high temperature resistance, good fatigue resistance and wear resistance.
With the rapid development of carbon fiber composite materials production and manufacturing processes, in the field of general aviation, carbon fiber composite materials have begun to be used more and more in the design of new aircraft due to their mechanical properties such as light weight, high strength and high specific modulus.

The entire fuselage of the UAV built by a US company is made of carbon fiber composite materials, such as spars, fuselage beams, horizontal stabilizers, and other structural components that are subjected to high loads are made of carbon fiber composite materials. Among them, the fuselage and wing surface skin adopt carbon fiber composite material interlayer design, the surface carbon fiber skin can be optimized according to the specific load distribution, and can increase the thickness of the carbon fiber around the door and window frame to increase strength.
In recent years, unmanned aerial vehicles have been more and more widely used in the field of general aviation due to their economic, safety and easy operation characteristics. Unmanned aerial vehicles have played an important role in areas such as earthquake prevention and disaster reduction, meteorological detection, traffic supervision, border patrol and land and resources monitoring.

The structure of carbon fiber composite materials used in small and medium-sized UAVs includes sandwich structure, laminate structure and pipe structure. The fuselage beam and tail brace are mainly laminated or wound tube structure, and the structural skin of the fuselage mainly uses the honeycomb sandwich or foam sandwich structure of the carbon fiber panel. The fuselage and wings of Thunderbird, China's first new energy drone, are also completely made of carbon fiber composite materials.
In recent years, airships have gradually become a hot topic in aviation research because of their advantages such as long empty time, large load capacity, low pollution, and low requirements for landing sites. In order to reduce the deadweight of the airship and increase the load, carbon fiber composite materials are used in the design and manufacture of airship structural framework, landing gear pods and other components.

With the rapid development of general aviation technology, the position of carbon fiber composite materials in the design and manufacture of general aircraft structural parts is becoming more and more important. Therefore, in the future, lightweight design development technology, low-cost manufacturing technology and rapid prototyping technology of large-scale carbon fiber composite materials components The meeting will become the key to promote the design and manufacture of China's general aircraft structure.
