arbon fiber materials are light and strong, and their physical and chemical properties are very good. Today, aircraft such as aerial cameras and plant protection machines tend to use this material. The fatigue limit of most metals is 30%-50% of their tensile strength. The fatigue limit of carbon fiber composites can reach 70%-80% of tensile strength, which can reduce the body damage caused by sudden accidents during use, with high safety and long service life. In addition to the use of a one-piece carbon fiber housing, the use of carbon fiber tubes as arm tubes and components for drones is also a very common form of application.
