Problems solved by technology

[0002] The automobile drive shaft is an important power transmission component in the automobile transmission system. Its function is to effectively transmit the power generated during the operation of the engine to the wheels together with the gearbox and drive axle to make the car generate driving force; the transmission system works in its own way. It will consume part of the energy of the engine due to its own weight. At present, the transmission shaft is mostly made of metal, and its own weight is relatively large, which will consume a large amount of energy from the engine.
[0003] Carbon fiber hybrid composite materials have excellent properties such as light weight, high strength, and friction resistance, and can be applied to transmission shafts with higher speeds and longer spans. At the same time, the composite material has a low thermal expansion coefficient, which can reduce transmission noise and vibration friction, effectively Improve the fuel efficiency of automobiles; although the composite transmission shaft prepared by the traditional two-dimensional winding method is light in weight and high in strength, it cannot meet the performance requirements of large torque
