Carbon Fiber Pultruded Tubing



Extremely stiff and lightweight tubes manufactured with standard modulus carbon fibers. The unidirectional fiber orientation offers incredible linear strength and are ideal in bending and tension applications.

Product Datasheet Icon


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.

Items starting with an “x” are product that are being sold as Clearance/Excess item(s). Items may be excess inventory that does not meet the stringent specifications of medical or aerospace applications, have blemishes and/or other imperfections as noted in the product descriptions. These items are sold “As Is”, are nonrefundable and will not be backordered. If an ordered quantity cannot be fulfilled, we will ship available on hand quantities and automatically cancel any remaining balance.



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)
