How Carbon Tubes Are Made

Carbon fiber tubes are ideal for both amateurs and industry professionals. Using the rigidity of the carbon fibers, an extremely stiff yet lightweight tubular structure can be used in a wide range of applications. Carbon fiber tubes can replace steel, but more often than not, it is replacing aluminum.

In many instances, a carbon fiber tube can weigh 1/3rd of an aluminum tube and still have the same or better strength characteristics. Because of this, carbon fiber reinforced tubes are often found in applications lightweight is crucial, like aerospace, race cars, and recreational sports.

The most common carbon fiber tubular profile shapes are squares, rectangles, and circular. The rectangular and square profiles are commonly referred to as a "box beam". Carbon fiber box beams provide excellent rigidity to a structure and simulate two parallel I-beams.

Carbon Fiber Tube Applications

For any application where weight is crucial, switching to carbon fiber will be beneficial. The following are some of the most common uses of carbon fiber tubes:

  • Aerospace beams and spars
  • Formula 1 structural components
  • Arrow shafts
  • Bicycle tubes
  • Kayak paddles

Manufacturing Carbon Fiber Tubes

Hollow composite structures can be difficult to manufacture. This is because pressure needs to be applied to both in internal and the external side of the laminate. More often than not, carbon fiber tubes with a continuous profile are manufactured by either pultrusion or filament winding.
