Carbon fiber composite drive shafts are not only lightweight but also boast excellent fatigue and corrosion resistance. They are also characterized by low noise levels, good vibration attenuation, and high safety, making them particularly suitable for heavy-duty drive shafts in large machinery. Carbon fiber composite drive shafts can be categorized into two types based on their structural design: integral and assembled. The integral type can be formed by continuous fiber weaving and curing, while the assembled type consists of two or more components connected to form a single unit. The assembled type drive shaft is widely used due to its simple manufacturing process and good mechanical properties.

The drive shaft primarily withstands torque during operation. One of the advantages of carbon fiber composite materials is their high tensile strength. To bear significant torque, the drive shaft must ensure the continuity of the fibers. The hand-laid-up process, which uses carbon fiber fabrics for production, requires the fabrics to be cut into various diameters and shapes according to specifications. This results in the fibers of each layer becoming individual entities without continuity, significantly reducing the torque-bearing performance of the carbon fiber tube.
