  • 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.
