High-end carbon fiber composite materials have the advantages of light weight, high strength, high specific stiffness, strong manufacturability, good fatigue fracture resistance, corrosion resistance, good dimensional stability and are conducive to large-volume integrated forming. They have been widely used in UAV processing. In addition, the use of integrated processing technology can process UAV parts, reduce the quality of the structure and reduce costs.

The use of carbon fiber composite materials in UAVs has gradually become a common trend. Overseas, common UAVs use a large number of low-cost, light-weight and high-strength composite materials in the fuselage structure, and have achieved rapid development and improvement in the aspects of raw materials, integrated manufacturing, analysis and processing technology of fuselage structure, resulting in a significant change in the overall design and processing technology of UAVs.

The application of carbon fiber composite material technology in the manufacture of UAVs has great advantages. Now let's make a concise and clear analysis for everyone.

(1) Aerodynamic advantages

UAVs will be subject to interference in lift, drag, force direction, magnitude, etc. in the navigation mode, and these aspects are affected by the raw materials, weight, manufacturing and other aspects of the UAV. Carbon fiber composite materials themselves are light and high-strength materials that can reduce gravity and resistance; the surface of the carbon fiber drone shell is smooth and the appearance is precise and symmetrical; and the carbon fiber drone shell adopts a molded-in-one processing technology during the production process, which can achieve a good level in quality and production.

(2) High structural strength

Good overall and local rigidity and high strength, high fatigue resistance, durability, fatigue damage resistance and fuselage stability; carbon fiber composite materials also have excellent corrosion resistance and heat resistance, and can withstand the erosion of sunlight, moisture, sand and dust in nature and the interference of thermal deformation, and can meet the special requirements of long-term storage service life of drones in various natural environment standards, reducing the life cycle cost of application maintenance.

(3) Quality

Compared with traditional metal materials and composite materials, carbon fiber composite materials have the characteristics of low density, high strength-to-rigidity ratio, small expansion coefficient, good fatigue resistance and strong seismic performance. Applying its technology to drone architecture can reduce the quality by 25%-30%. Improve rationality and effectiveness;

(4) Processing technology and economy

UAVs have a highly wing-body integrated flying wing aerodynamic design, which requires a large-volume integrated forming method for the structural type. After simulation and calculation, carbon fiber composite materials can not only realize large-volume integrated forming through molding, autoclave curing and other processing technologies, but also introduce automated production line processing technology, optimize UAV processing equipment, reduce assembly workload, reduce processing cycle time, and reduce the cost of the entire machine throughout its service life.

In addition, the mechanical properties of carbon fiber materials are outstanding. Its compressive strength, flexural strength, and shear strength are better than most structural materials, which can reasonably meet the high strength requirements of UAVs during the entire application process. Carbon fiber is a common non-metallic material with low electrochemical activity. It can operate smoothly in harsh outdoor environments or chemical corrosion and wet and cold environments. It has a long service life and can meet the requirements of UAVs during flight.
