Carbon fiber composite materials have the characteristics of light weight, high specific strength and specific modulus, and are often used in the design of UAV composite material structures. Carbon fiber composite materials have strong designability. They can design lightweight, highly aeroelastic structures, spray stealth coatings on their surfaces, and reduce the damage tolerance of carbon fiber composite materials at high speeds. In addition, chips or sensors can also be embedded in the composite matrix structure to form real-time monitoring of smart materials and structures.

In the design of UAV composite structures, the axial performance of carbon fiber composites and the designability of the fiber direction of the laminate should be fully utilized. Suzhou Noen Composite Materials Co., Ltd. masters the research and development of carbon fiber composite materials and the design and simulation calculation of aviation structural parts. According to research experience, the common structures used on drones include sandwich structures and laminate structures. For example, the fuselage structure consists of longitudinal beam flanges and skins. and horizontal frame.
In the design of the UAV composite material structure, the structural stiffness and structural elasticity distribution of the UAV are mainly achieved through different laying angles and different layer designs. For example, the Helios solar UAV in the United States, the main structure of the UAV is Made of carbon fiber reinforced epoxy resin composite material, the coupling effect produced by the asymmetric and non-equilibrium lamination of the composite material is used to perfectly combine the structural stiffness and structural elasticity design of the composite material.
In addition, small UAVs generally have performance deficiencies such as low flying height, small payload, slow speed, and short endurance. When operating in complex environments, the frequency of damage to the aircraft body is also relatively high. Traditional metal materials such as aluminum alloy are far from enough. The development needs of drones in terms of performance.
Carbon fiber composite materials have high specific strength and high specific stiffness. As far as the material itself is concerned, the use of carbon fiber composite materials can reduce the weight of at least 30% more than aluminum alloy materials, which can greatly reduce the weight of the drone's fuselage, thereby increasing the number of drones. The payload capacity can extend the flight distance and time of the aircraft body, making it an ideal material for lightweight, miniaturization and high performance of UAV structures.
In order to meet the high-performance requirements of UAVs, carbon fiber composite materials have received widespread attention and application due to their superior performance. Therefore, in the future, lightweight design and development technology, low-cost preparation technology, rapid prototyping and other aspects of large-scale components of carbon fiber composite materials will be used. This advanced technology is a key technology to maintain the structural design of my country's general aircraft. As a well-known advanced carbon fiber structural parts manufacturing enterprise in China, Dongguan One Victor Composite Technology Co., Ltd. has been committed to the design and development of composite materials and the design of aviation structural parts. Maximize the realization and utilization of the special advantages of carbon fiber composite materials.
