Tube - Square - Plain Weave - High Modulus - 0.005 Glass Weave Outer - 1.000 x 1.098 x 45 inch
High performance tubing built without compromise Rock West's high modulus tubing utilizes high modulus (55 Msi) fibers with a strength of 640 ksi. This combination yields an astounding product comprised of a multi-directional layup of only high modulus fibers with a higher temperature resin system. Our high modulus tubing lineup is generally designated by using an outer layer of a 3k plain weave fabric.
- 55 msi Unidirectional carbon fiber throughout with a
- Standard Modulus plain weave outer woven layer for increased performance when machining and hole drilling
- Can easily be trimmed into shorter lengths for your complete build
- Nearly 2x stiffer than all standard modulus tubes
- *Estimated to have a composite elastic modulus of ~19Msi
*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. Consider bending the tube over your knee.
- 45° Fibers maximize torsional stiffness. Typically plied together in an opposing manner, i.e. ±45°. Consider twisting the tube like a vehicle's driveshaft.
- 90° Fibers maximize crushing stiffness and generally assist in overall tube strength. Consider laying the tube on the ground and stepping on it.
