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.

Skin

The skin of a 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.

Wings and tail wings

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

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 structures, but also improve energy absorption and shock absorption capabilities, which can protect the safety of the drone during landing.

Rotors and propellers

For multi-rotor drones, rotors and propellers are crucial. Carbon fiber composite materials can be used to manufacture lightweight and strong rotors and propellers by optimizing material formulation 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.

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 while ensuring the stable operation of these key components in harsh environments.

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 bolt connection, riveting, etc.) to ensure the overall structural stability of the drone.

The main carbon fiber materials used in drone production 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 prepregs are 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 desired shape to provide strong and lightweight structural support for drones.

In addition, the application of carbon fiber fabrics and prepregs in drone manufacturing is also reflected in their excellent designability. Through reasonable material layout and structural design, the performance of drones can be further optimized, such as increasing flight speed, increasing load capacity and extending flight time. At the same time, the lightweight characteristics of carbon fiber materials also help to improve the endurance of drones, enabling them to perform well in long-distance flights or complex tasks.

The fuselage of a drone is the main component of the entire drone and the flight carrier of the entire flight system. Generally, high-strength and lightweight materials are used. The main materials currently include: ABS/modified PC and its alloys, carbon fiber materials, aviation aluminum, advanced composite materials, etc.

Among these commonly used materials, carbon fiber composite materials have played an outstanding advantage. Carbon fiber is a fiber made of chemical fiber and petroleum by a special process. In addition to having the same high temperature resistance, friction resistance, electrical conductivity, and thermal conductivity as general carbon materials, it has higher strength, lighter weight, and more corrosion resistance.

The density of carbon fiber is less than 1/4 of that of steel, but its tensile strength is 7 to 9 times that of steel, and its tensile elasticity is also higher than that of steel. In an inert environment with a high temperature of more than 2000°C, it is the only material whose strength does not decrease. It does not dissolve or swell in organic solvents, acids, and alkalis, and its corrosion resistance is outstanding.

From the perspective of use, carbon fiber does not have the problem of corrosion and rust, and is more durable than ordinary metals. Under extreme climatic conditions, the properties of carbon fiber hardly change. Application in drone fuselages can improve overall performance. At the same time, the use of integrated manufacturing technology can produce drone accessories, reduce structural weight, and reduce production costs.
