Round Carbon Tubes

Pultruded round carbon fiber tubes are created by pulling linearly-oriented carbon fibers through a resin bath and then a series of heated tooling to create the specified inner and outer diameters of the tube. Carbon tubes are especially stiff longitudinally, due to the unidirectional orientation of the fibers. These tubes are stiff, lightweight composites that can be used in a variety of applications, including robotics, aerospace, industrial equipment, and more.

We offer carbon fiber tubing in a variety of stock outer diameters from .125” to .750”. All lengths listed are +/- 0.062″ and all diameters listed are within +/- 0.005″. We can custom cut your order to a specific length and we’d be happy to speak with you about large, custom orders or machining. Contact us at [email protected] or 206-632-6151 to speak with a composites engineer.
