    • ~0.005 reduction on outer diameter (OD)."
    • This removes the outer cello wrap gloss finish.
    • Sand outer diameter to specified thickness.
    • Patterns will likely distort in appearance

If you are requesting bulk discounts, cutting, or standard sanding services only, we will send you a cart with your product selections. You may enter your shipping information and purchase directly at that time. Please note, the cart will not allow edits to the quote. Any changes will have to be completed by our team. If we do not have enough information to complete your quote we will reach out to you directly. If you are requesting additional services or custom sanding, a team member will reach out to you to finalize a quote.

If you request a custom length you will be charged for a full length item (or items if more than 1 is needed to meet your request) plus a cutting fee. You will then be shipped the item sized to your specification and any remaining length of the orginal item (drops). Sanding also incurs a fee which will be included in the quote. All items that have been sanded or cut may not be returned.

Description

Unlike metals which have similar properties in all directions (isotropic), the properties of composites are varying, dependent on the orientation of the fibers in each layer. 

Roll wrapped tubing is manufactured using multiple layers of pre-preg carbon fiber (and if noted, other) materials. In general each layer is about 0.006 inches thick which means that a tube with a wall thickness of 0.060 inches will typically be composed of 9-10 individual layers of carbon fiber. The number of layers(plys) allows us to vary the orientation of the fibers throughout the thickness, creating a high performance, engineered product.
  • Fabric Tubing has an outer ply of woven material (denoted below as 0°/90°). Typically this outer ply is a 2x2 twill weave (diagonal appearance seen below) but it can also be a plain weave (small checkerboard), spread tow (large format plain weave / checkerboard) or other off-axis weave such as a braid. The core of these tubes are almost always comprised of multi-directional "uni" plies.
  • Uni Tubing is comprised of multi-directional "uni" plies just like the fabric tubes however instead of the outer ply being fabric, it is unidirectional and most typically oriented at 0° (fibers running the length).

  • 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.
