Since the invention of unmanned aerial vehicle (UAV), reducing weight has become one of the research hotspots of common attention of uav scientists all over the world. Only by reducing the structural mass of the body. To save more mass space to increase fuel and payload, and to extend flight range and endurance. As carbon fiber composite materials are widely used in large civil aircraft, they are also considered to be the best choice to solve the mass reduction problem in uAVs. Compared with traditional metal materials and composite materials, carbon fiber composite materials have the characteristics of light weight, high strength, anti-fatigue and anti-salt spray erosion. Applied to uav structure, the comprehensive performance of uav can be greatly improved. According to statistics, at present, advanced composite materials based on carbon fiber composites are widely used in uav in all countries in the world, accounting for 60% ~ 80% of the total mass fraction of the structure, which reduces the body mass by more than 25%. The application of carbon fiber composite material plays a vital role in the lightness, miniaturization and high performance of uav structure.
Application advantages:
1. The specific strength and stiffness than large compared to the other composite materials, in the unmanned aerial vehicle (uav) under the premise of the same body strength and stiffness, specific strength and specific stiffness features of carbon fibre composite material can greatly reduce the structure of the unmanned aerial vehicle (uav) is an, miniaturization and high performance-based is of great significance, to ensure that the distance and time of flight of unmanned aerial vehicle (uav) have a long flight.
2. Integrated forming UAVs often require a flying wing type overall aerodynamic shape with high wing-body fusion, which needs to adopt large-area integrated forming technology in structure. After the simulation and simulation calculation, the carbon fiber composite material can not only be molded by molding, curing outside the autoclastic tank or RTM resin transfer molding, etc.
3. Good corrosion resistance and heat resistance Carbon fiber composite material also has excellent corrosion resistance and heat resistance, can withstand the corrosion of water and a variety of media in nature and the influence of thermal expansion, can meet the special requirements of uav long storage life under various environmental conditions, reduce the life cycle cost of use and maintenance.
4. Implantable chips or alloy conductors Carbon fiber composite materials can also be implanted with chips or alloy conductors, forming a structure with intelligent whole, can be used in harsh environment for a long time. Without damaging the performance of the implanted device, it can reliably perform special tasks. Application status: Due to many advantages of carbon fiber composite materials in uav application, in recent years, a large number of advanced uAVs at home and abroad have used carbon fiber composite materials
