Carbon fiber composite drive shafts are not only lightweight but also boast excellent fatigue and corrosion resistance, with low noise, good vibration attenuation, and high safety, making them particularly suitable for large heavy-duty drive shafts. Carbon fiber composite drive shafts can be categorized into two types based on their structural forms: monolithic and assembled. Monolithic structures can be formed through continuous fiber weaving and curing, while assembled shafts are made by connecting two or more components into a single unit. Assembled drive shafts are widely used due to their simple manufacturing process and good mechanical properties. The drive shaft primarily withstands torque during operation. One of the advantages of carbon fiber composites is their high tensile strength. To bear large torques, it is crucial to ensure the continuity of the fibers. Hand-laid-up molding technology, 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 in each layer becoming individual units without continuity, significantly reducing the shaft's torque-bearing capacity.
