In recent years, with the gradual development of low altitude airspace in China, the general aviation industry has developed rapidly. With the advantages of small density, high specific strength and specific modulus, good high temperature resistance, good fatigue resistance and wear resistance, carbon fiber composite has been widely used in the design and manufacture of general aircraft.
With the rapid development of production and manufacturing technology of carbon fiber composite, carbon fiber composite has been used more and more in the design of new aircraft because of its advantages of light weight, high strength and high specific modulus.
Carbon fiber UAV
The overall fuselage of the UAV built by a company in the United States is made of carbon fiber composite materials, such as wing beams, fuselage beams, horizontal stabilizers and other high-load structural members are made of carbon fiber composite materials. Among them, the fuselage and wing skin adopt carbon fiber composite sandwich design, the surface carbon fiber skin can be optimized according to the specific load distribution, and can increase the thickness of carbon fiber around the door and window frame to improve the strength.
In recent years, UAV is more and more widely used in general aviation because of its economy, security and easy operation. For example, UAV plays an important role in earthquake prevention and mitigation, meteorological detection, traffic supervision, border patrol and land and resources monitoring.
Consumer grade carbon fiber UAV
The carbon fiber composite structure used in small and medium-sized UAV includes sandwich structure, laminate structure and pipe structure. The main body of the fuselage beam and the tail support are mainly laminates or winding pipes. The structural skin of the body mainly adopts honeycomb sandwich panels or foam sandwich structures with carbon fiber panels. The fuselage and wings of Thunderbird, the first new energy UAV in China, are also made of carbon fiber composite materials.
In recent years, airship has become a hot topic in the field of aviation because of its advantages, such as long time in the air, large load, small pollution and low requirements for the landing site. In order to reduce the weight of airship and improve the load, carbon fiber composite materials are used in the design and manufacture of airship structure framework, landing gear pod and other components.
Carbon fiber UAV shell
With the rapid development of general aviation technology, carbon fiber composite plays an increasingly important role in the design and manufacture of general aircraft structural parts. Therefore, the lightweight design and development technology, low-cost manufacturing technology and rapid prototyping technology of large components of carbon fiber composite will become the key to promote the design and manufacture of general aircraft structures in China in the future.
