Our Carbon Fiber Pultruded Tubes are manufactured by pulling continuous carbon fibers combined with a resin matrix through a heated steel forming die. This process is referred to as pultrusion and is used for producing continuous lengths of composite materials with constant cross-sections.

As the carbon fibers are saturated with the resin mixture and then pulled through a die, the hardening of the resin is initiated by the heat from the die and a rigid, cured tube is formed in the shape and size of the die. The majority of the fibers are running in the 0 degree direction, along the length of the tube, to produce an extremely stiff and lightweight tube with a very low coefficient of expansion. This type of construction offers a high stiffness to weight ratio tube with incredible linear strength, due to the orientation of the carbon fibers, and tight outer diameter (OD) tolerances.

Our Pultruded Carbon Fiber Tubes have a matte finish surface and are covered with a light glass scrim to improve structural integrity of the tube.

How to Guides

The Do's and Don'ts of Cutting Composite Tubes and Rods


Q: What is the difference between the series?

A: Series are used to segment items with differing physical and/or technical properties. Please review the product data sheets for comparison.

Q: How is the wall thickness calculated?

A: Subtract the inner diamter (ID) from the outer diamer (OD) and divide that number by 2. Example: 1.624"OD-1.50"OD= .124". .124"/2=.062" Wall thickness (WT)
