Features & Benefits
Roll wrapped tubing is manufactured using multiple layers of prepreg 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.

- 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.
