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 large heavy-duty drive shafts. Carbon fiber composite drive shafts can be divided into two types based on their structural forms: integral and assembled. The integral structure 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 drive shaft is widely used due to its simple manufacturing process and good mechanical properties.
