Tube - NB321 - HR40 Uni AS4 Plain Weave Outer - With Traceability - 0/0/45/-45/0/0/-45/45/0/0/(0/90) 1.000 x 1.091 x 96 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)

- 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.
