"Moving forward with heavy load" has brought a lot of problems to UAVs in terms of energy consumption and power loss. As the current global energy crisis and environmental pressure continue to intensify, UAV manufacturers are accelerating the development of weight-reducing products. Therefore, lightweight is the goal that UAV applications have been pursuing. Reducing the dead weight of UAVs can increase the endurance time of UAVs and reduce energy consumption. In this paper, the application advantages of carbon fiber materials in UAV shells are analyzed.

First of all, let's take a look at the advantages of carbon fiber composite materials. Compared with traditional metal materials, carbon fiber composite materials have a relative mass density of only 1/4~1/5 of steel, but their strength is six times higher than that of steel. The specific strength is twice that of aluminum alloy and four times that of steel, which is in line with the demand for lightweight UAVs. Moreover, the carbon fiber composite material has a small thermal expansion coefficient and good structural stability. It will not cause deformation of the UAV shell due to the change of external temperature, and it has good fatigue resistance and good earthquake resistance.

Carbon fiber composite material has a good performance advantage, which makes the UAV shell made of carbon fiber composite material also a very good advantage. The forming process of a carbon fiber UAV shell is simple, the production cost is low, and the casing integration can be realized. It has strong designability, which can provide more energy reserve space for the UAV, and provide broad freedom for the optimal design of its structure.

The UAV needs to be combined with pneumatic technology in the flight process, and the effect of wind resistance should be considered in the design. The carbon fiber composite material has very good designability, which can well meet the needs of the UAV shell. At the same time, the shell of the UAV made of carbon fiber composite material also has very good corrosion resistance, which can still maintain the stability of the whole structure under acid, alkali, and salt corrosion. This also makes the application scenario of UAV more and more and improves the overall application of UAV. It has the advantages of reducing vibration and noise and reducing interference of metal materials to remote signals.

In addition, the carbon fiber composite material has the advantages of reducing shock and noise, reducing interference to remote signals, and can achieve stealth because of its electromagnetic shielding performance
