Customized Carbon fiber UAV parts refer to various parts of UAVs made of carbon fiber composite materials, including the chassis, wings, rotors, tail struts, etc. Carbon fiber UAV parts are widely used in the chassis, wings and rotors, tail struts, etc.

Carbon fiber UAV parts

UAVs refer to unmanned aerial vehicles that use aerodynamics as the source of lift, referred to as UAVs. Originally developed for military applications, they were later expanded to commercial, logistics, entertainment, and agriculture. According to their uses, UAVs can be divided into civil UAVs and military UAVs. Among them, civil UAVs can be divided into industrial UAVs and consumer UAVs. Consumer UAVs are usually used for daily purposes such as entertainment and aerial photography, while industrial UAVs are widely used in agriculture, logistics, surveying and mapping, etc. Military UAVs are mainly used for reconnaissance, surveillance, and combat missions.

There are many types of UAV parts, including but not limited to motors, electronic speed control, sensors, cameras, antennas, main control chips, batteries, radars, gyroscopes, cameras, engines, electric regulators, remote control receivers, etc. The manufacturing of these parts involves precision machining, materials science, electronic information technology and other fields, and has extremely high requirements for technical level and production capacity.

At present, countries around the world use a large amount of carbon fiber materials in the production and manufacturing of drones. The use of carbon fiber materials accounts for 60%-80% of the structure of drones. In the production and manufacturing of drones, it involves fuselage frames, skins, wings and tail wings, landing gear, rotors and propellers.

Lightweight, high-strength and electromagnetic concealment drone revolution

The density of traditional metal materials steel is 7.8g/cm³, the density of engineering plastics is 2.2g/cm³, and the density of carbon fiber materials is 1.6g/cm³, which can well reduce the energy consumption of drones, improve endurance, and escort for long-term work.

High strength and good load-bearing performance

Carbon fiber composite materials are better than engineering plastics in lightweight performance, and are much higher in strength than engineering plastics. The tensile strength of carbon fiber can reach 3600MPa. It can improve the load-bearing performance, carry more instruments and equipment, and the overall structural stability is also improved, and it can ensure good stability even when it hits an obstacle.

Electromagnetic concealment

Carbon fiber composite materials can have special electromagnetic properties. Adding fiber materials and inorganic particles with wave-absorbing and wave-transmitting properties to the carbon fiber, or spraying stealth coatings on its surface, can reduce the radar, infrared, optoelectronic and other observation characteristics of the drone, and improve the survivability and combat effectiveness of military drones. In addition, by optimizing the design of the drone body structure, implanting various special-shaped wave-absorbing and wave-transmitting composite structures in the body, or smoothing the surface of the body and various joints, the radar cross-section value is reduced, and the electromagnetic concealment of military drones is improved.

Acid and alkali corrosion resistance, long service life

Commonly used carbon fiber composite materials are made of carbon fiber and epoxy resin. Unlike metal materials, carbon fiber composite materials will not react chemically with substances such as acids, alkalis, and salts. In extreme environments such as exposure to the sun, cloudy and rainy, the service life of the drone will also be greatly improved.

① Fuselage frame

The high specific strength and specific stiffness characteristics of carbon fiber composite materials can not only ensure the structural strength of the fuselage, but also greatly reduce the weight of the fuselage, which is crucial to improving the endurance and flight-related performance of drones. If combined with integrated molding technology, it can simplify the manufacturing process of drones, improve the overall structural stability, and enhance the load capacity.

② Skin

The skin of the drone not only protects the internal equipment, but also has an important impact on the aerodynamic performance of the drone. The skin made of carbon fiber composite materials has a smooth surface, accurate shape, and good symmetry, which can reduce air resistance and improve the flight speed and efficiency of the drone. At the same time, the carbon fiber skin also has good fatigue resistance and durability, and can adapt to long-term flight missions.

③ Wings

The wings and tail are key components for drones to generate lift and control flight attitude, and the performance requirements of the materials are very high. The high strength and lightweight characteristics of carbon fiber composite materials can provide sufficient lift and good control performance for the wings and tail. In addition, the anisotropic properties of carbon fiber can meet the mechanical performance requirements of the wings and tail in different directions through reasonable layer design, and improve the flight stability and maneuverability of the drone.

④ Landing gear

The landing gear is a key component of the drone when landing and needs to withstand huge impact loads. Carbon fiber composite materials not only reduce weight through reasonable structural design, such as the use of honeycomb sandwich structure, but also improve energy absorption and shock absorption capabilities, which can protect the safety of drones when landing.

⑤ Rotors and propellers

For multi-rotor drones, rotors and propellers are crucial. Carbon fiber composite materials can produce lightweight and strong rotors and propellers by optimizing material formula and molding process, reducing air resistance and improving lift efficiency. At the same time, the anti-fatigue performance of carbon fiber composite materials also ensures the stability and reliability of drones during long-term flight.

⑥ Battery box and fuel tank

Carbon fiber materials are also commonly used to make components such as battery boxes and fuel tanks. Due to their light weight, high strength and corrosion resistance, they help reduce the overall weight of drones and ensure the stable operation of these key components in harsh environments.

⑦ Connectors

The various components of fixed-wing drones need to be connected through connectors. Carbon fiber composite materials have excellent connection properties and can be firmly connected to other components through various connection methods (such as bolting, riveting, etc.) to ensure the overall structural stability of the drone.

The main carbon fiber materials used in the production of drones are carbon fiber fabrics and prepregs. Carbon fiber fabrics, as the basic material for drone structural parts, are known for their high strength, low weight, corrosion resistance and excellent thermal stability. In the manufacturing process of drones, carbon fiber fabrics are often used to make wings, fuselage frames and other key load-bearing components. This material can not only effectively reduce the overall weight of the drone and improve flight efficiency, but also maintain structural stability and durability in extreme environments. Through precise cutting and sewing processes, carbon fiber fabrics can be processed into various shapes and sizes to meet the diverse needs of drone design. Carbon fiber prepreg is another important composite material in drone manufacturing. Prepreg is obtained by impregnating carbon fiber fabric with a specific type of resin matrix under strictly controlled conditions. After curing, this material can form a structural part with high strength, high modulus and good fatigue resistance. In the production process of drones, carbon fiber prepreg is often used to make complex structural parts such as landing gear, engine brackets and battery compartments. Through processes such as compression molding and autoclave curing, carbon fiber prepreg can be precisely processed into the required shape, providing strong and lightweight structural support for drones

Using the intelligent processing technology of the five-axis machining center, this technology can ensure the precise size of each component and ensure the accuracy and performance of drone assembly. It enhances plasticity and improves  performance, and is increasingly used in the field of low-altitude flight.
