Three advantages of carbon fiber drive shaft:

First of all, from the perspective of strength, although carbon fiber is a fiber material, the strength of the product after it is formed is better than that of most structural materials, especially it has good bending strength and can withstand greater than metal drive shafts.

At the same time, the tensile strength of carbon fiber material is several times that of steel, and the shear strength is also better than that of most structural materials, which meets the needs of use strength.


Carbon fiber is a good weight-reducing material. Its density is only 1.7g/cm3. The density of commonly used structural materials aluminum and steel are 2.7g/cm3 and 7.85g/cm3 respectively. In comparison, the drive shaft made of carbon fiber is more Conducive to the realization of the structure

Lightweight, when the body structure is lightened, it will help to realize the energy saving and emission reduction of the car.

Finally, the critical speed refers to the speed at which the rotor vibrates strongly. Generally, when the rotor is running at the critical speed, severe vibration occurs, and the curvature of the shaft increases significantly. Long-term operation will cause serious deformation or even breakage of the shaft.

The driven shaft has a high critical speed, which can effectively avoid such problems.

When the resin, curing agent and other materials are mixed in a certain proportion, and then the carbon fiber fabric is infiltrated, after a series of curing treatments, a carbon fiber composite material is formed, which is the black lattice material that we can often see on the car.This material has advantages that traditional metal materials can't match.

However, the carbon fiber transmission shaft is not entirely composed of carbon fiber. Instead, the skeleton of the transmission shaft is first made of a metal mesh material, and a whole bunch of carbon fiber filaments with a total length of over 100 meters are spirally wound around the metal skeleton.
