Carbon fiber composite drive shafts are not only lightweight but also boast excellent fatigue and corrosion resistance. They are characterized by low noise, 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 forms: integral and assembled. The integral type can be formed through 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 large torques, the drive shaft must first ensure the continuity of the fibers. The hand-laid-up process, using carbon fiber fabric for production, requires the fabric to be cut into various diameters and shapes as specified. This results in the fibers in each layer becoming individual units without continuity, which significantly reduces the tensile performance of the carbon fiber tube.
