3 Advantages of Carbon Fiber Drive Shaft

1.High strength

The carbon fiber used in the carbon fiber drive shaft is mainly made of polypropionitrile fiber, which is processed into extremely fine fiber filaments through special processes such as high-temperature carbonization, which improves the strength of the monofilament and increases the surface area of a certain amount of fiber 3 times, stiffness higher than 2 times, fatigue resistance higher than 2 times, it is a very attractive fiber reinforced material, with high strength, high modulus, high temperature resistance, wear resistance, corrosion resistance, fatigue resistance and many other excellent properties. The strength of general-purpose carbon fiber is 3,500MPa, which is much higher than the strength of steel 340Mpa.


2.Lightweight
The density of carbon fiber material is 1.8 g/cm3, and the density of steel is 7.8 g/cm3. The data shows that the carbon fiber composite transmission shaft can reduce the mass by at least 40% compared with the traditional metal transmission shaft, including the metal link parts of the two sections of the transmission shaft. For every 1% reduction in the mass of common parts of automobiles, 1% of fuel can be saved, and moving parts such as transmission shafts can save 2% of fuel.


3.High critical speed
Among the many performance parameters of the automobile drive shaft, the critical speed is a very important parameter. When the rotation speed of the transmission shaft is the same as the natural frequency of its bending vibration, the transmission shaft will resonate and there is a danger of breaking. The carbon fiber composite transmission shaft has excellent mechanical properties and displacement compensation capability, and a single shaft tube can meet the requirements of use.


We have first-class production line and strict management system.
