Carbon fiber composite drive shafts are not only lightweight but also boast excellent fatigue and corrosion resistance, with low noise levels, good vibration attenuation, and high safety. They are 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 forms: 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 first ensure the continuity of the fibers. Hand lay-up technique is used, producing with carbon fiber cloth. The carbon fiber cloth must be cut to various diameters and shapes as required, making each layer of fibers individual and non-continuous, which would greatly reduce the torque-bearing performance of the carbon fiber tube.
