Carbon fiber is the ultimate driveshaft technology. It's also the most costly material in the lineup. Carbon fiber is the strongest material in terms of strength and weight, and it's also a great dampener.
The Production of Carbon Fiber Driveshafts
It is a fascinating process to create a carbon-fiber driveshaft. Most people don't get the chance to witness it. To achieve the desired strength characteristics, the manufacturing process begins with "wet-winding" carbon fiber onto steel mandrels at various angles. The carbon fiber tube is then bonded to the steel or aluminum ends. You can get more information about carbon fiber driveshaft via https://pstds.com/driveshafts/carbon-fiber-driveshaft.

Once the carbon fiber tube has been received by their tube manufacturer, the ends of the tube are welded to the application. Finally, the shaft is completed with a slip yoke and U-joints.
Chromoly, in terms of carbon fiber, is only a hundredth of a pound more than mild carbon. This means that the whole shaft is one pound heavier. Carbon fiber, meanwhile, is only .18 pounds lighter per foot than aluminum, so your average 48-inch driveshaft would only save you about .63 pounds all said and done.
No matter what material you choose, all driveshafts have the same U-joints, slip yoke. These are the heaviest parts of a driveshaft. This is because there isn’t much difference in the weight of each material. Budget-minded people could probably put that money to better use.
The critical speed of carbon fiber drive shafts is dependent on their length and diameter. This equation is dependent on the module of elasticity in the shaft material. These numbers are difficult to find as many shops do not keep exact numbers. The basic MOE for carbon fibre driveshaft is 10. Carbon fibre driveshaft is dependent on the manufacturing process used so there are no numbers.
