Carbon Fiber Tubes
Carbon fiber tubes are ideal for both the hobbyist and industry professional. 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 light weight 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.
