Tube - Filament Wound - HS40 Torque Layup - Unsanded - 0.75 x ~0.95 x 12 inch - - Available up to 96 Inches
There is a $15 cutting charge for each tube ordered that has a length less than the maximum available tube length. The standard cutting tolerance on these tubes is 0.125”.
Please note we cannot control the OD of unsanded filament tubing as tightly as the sanded filament tubing. The listed OD is a theoretical value.
Void of compromise and full of intense performance! Rock West's high modulus tubing utilizes a high performance resin system giving it a higher Tg and special hardening agents. Filament Wound Carbon Tubing is a very long continuous fiber that adds to strength and stiffness. Filament wound tubes are excellent for torsion, long single-piece tubes, and a unique aesthetic. Most economical for larger scale production. The unsanded finish on this tube is less controlled, so the listed OD is theoretical. To control the tolerance on the OD of this tube we suggest you have it sanded. This unsanded carbon fiber filament wound tube has a 0.750" ID x 0.950" OD and is sold by the foot. The longest continuous length available for this tube is 108" long.
0.750" ID Filament Wound High Modulus Tubing Facts

*This value varies depending on the specific layup orientation, tube diameters and shape. Representing a theoretical modulus assigned to a general composite round tube (not the fiber alone)
Features & Benefits
Carbon Fiber Material | Modulus, Strength | Benefits, Features & Notes
- Standard Modulus | 34 msi, 700 ksi | Good structural properties - Stiffer than aluminum - Readily available
- Intermediate Modulus | 42 msi, 825 ksi | Great structural properties - Highest strength option - Great balance of stiffness and strength
- High Modulus | 57 msi, 670 ksi | Very stiff - Good thermal conductivity / stability - Typically used in all 0° & 90° (or off-axis) plies throughout the ply sequence / laminate orientation.
- Ultra High Modulus | 94 msi, 414 ksi | Stiffest option available - Great thermal conductivity - Used primarily as 0° plies in combination with lower modulus / higher strength fibers in the 90° orientation to create a well-balanced and functional composite structure.
*Values listed above are reflective only of the fiber NOT the composite matrix (fiber + resin) and are listed only for tensile modulus and strength. ***Theoretical values are currently not available for this tube but testing can be performed upon request for a fee

- 0° fibers maximize bending stiffness and run along the length of the part. Consider bending a tube over your knee.
- 45° fibers maximize torsional stiffness and are typically plied together in an opposing manner, i.e. ±45°. Consider twisting a tube like a vehicle's driveshaft.
- 90° (or "hoop") fibers maximize crushing stiffness and generally assist in overall durability. Consider laying a tube on the ground and stepping on it.
