Carbon Rods

Solid Round Carbon

 

Our pultruded carbon rods have a high fiber volume fraction and are available in very small diameters (as small as 0.020” and as large as .750” in diameter). The higher the fiber volume fraction, the stiffer the rod will be for a given diameter. These rods are available in round or flat profiles in continuous lengths of up to 5000 feet up to .156” in diameter.  Continuous lengths in larger diameters are also possible, but require special coiling considerations.  Please contact us at 360-588-4785 or info@goodwinds.com for more information.
