Tube - Plain Weave - High Modulus - 1.500 x 1.75 x 72 Inch
Void of compromise and full of intense performance! 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
Fabric roll wrapped tubing offers many benefits over uni-directional and even filament wound tubing. That isn't to say it is the best however. Here are a few reasons you may wish to consider fabric roll wrapped tubing for your application.
- Superior machine ability
- Much better durability by reducing the potential extent of fiber breakout if drilled, machined or damaged
- Typical aesthetic associated with carbon fiber products
- Most "fabric" tubes contain a majority 0° plies in the layup allowing for the most effective bending load support. (whereas filament wound tubes cannot achieve angles less than ~7°
To meet growing market demand, Rock West Composites is now selling an Economy line of tubes and plates. These products provide a lower bar for entry for customers looking to incorporate carbon fiber and other composites into their projects. This low-cost line is sourced internationally and is best utilized in applications that do not have engineering critical features, but has the convenience of shipping from our Utah operation for expedient delivery.
Our premium Rock West tubes and plates are manufactured to our exacting standards in-house. The result is greater strength and stiffness with guaranteed consistent layups, tolerances, and test results. If you need help deciding what is right for you, please contact us and we’ll assist you as best we can.

- 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.
