Carbon fiber composite drive shafts are not only lightweight, with excellent fatigue and corrosion resistance, but also feature low noise, good vibration damping, and high safety, making them particularly suitable for heavy-duty drive shafts in large machinery. Carbon fiber composite drive shafts can be divided into two types based on their structural forms: monolithic and assembled. Monolithic structures can be formed by continuous fiber weaving and curing, while assembled shafts are composed of two or more components connected to form a single unit. Assembled drive shafts are widely used due to their simple manufacturing process and good mechanical properties.
