A drive shaft is a mechanical component for transmitting torque and rotation. It is used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them. The drive shaft takes a lot of stress, so it must be straight, strong, and durable.
In the video below you will see a test of a carbon fiber drive shaft vs. steel drive shaft! The test is simple – they are twisted with force until they break. Which one might be stronger?
Most of the vehicles are equipped with a steel drive shaft. Also many components on cars are made of steel. Steel is worldwide material, because of its strength and low cost. But it tends to twists when you’re making a good amount of power and it’s heavy.
On the other hand – carbon fiber is more expensive, but it is lighter and much stronger than steel. The carbon fiber shaft didn’t even look deformed, while the steel shaft was deformed under the same amount of twisting pressure.
