Tube - 1k Plain Weave - Ultra High Modulus - 0.25 x 0.50 x 72 Inch
Introducing extreme. Rock West's ultra high modulus tubing utilizes pitch based carbon fibers in the 0 degree orientation to yield the stiffest composite tube yet. Our 0.250"ID x 0.50" OD ultra high modulus tubing lineup is designated generally by using an outer layer of a 1k plain weave fabric.

- 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.
