Carbon Fiber in Aviation Accessories
The use of carbon fiber reinforced polymer matrix composites (CFRP) in civil aviation aircraft and helicopters is growing, such as the United States. The weight of CFRP in Chinese Boeing 787 and European Airbus A350XWB7 has exceeded 50%. Compared with traditional aviation materials such as metal aluminum and titanium alloy, the excellent performance of CFRP is the key to its wide application. These properties include: light weight, high strength, corrosion resistance, etc. Especially the excellent fatigue resistance of CFRP makes it the material of choice for helicopter structures and aircraft components.
In helicopters, examples of CRFP gaining widespread use include the new Sikorsky CH-53K and Airbus Helicopters. The H160, of which the CH-53K was released in 2016, was the first CH-53 model to feature a fuselage side shell made of CFRP, while the H160 launched in 2015 became a civilian helicopter with a full CFRP body. To realize the full potential of CFRP in helicopter structures, sophisticated fabrication techniques must be used. Autoclave Thermoset Prepreg
Material technology is currently the main manufacturing method for composite parts of aircraft and helicopter structures. This manufacturing process provides high part quality and high fiber volume fraction, and is capable of producing complex monolithic parts such as the Airbus Helicopters H145 Fenestron TM shroud.
The application and development of fiber-reinforced composite materials in the field of helicopters is shown in the figure below. After decades of development, compared with civilian direct. The content of CFRP in the lift is less than 70%, and the amount of CFRP in the structural materials of military helicopters has exceeded 80%.
