Roll Wrapped High Performance Carbon Fibre Tube 3k For Use In Projects Requiring Enhanced Strength In Multiple Axis. Whether your project is big or small, we are bound to have round carbon fiber tubing that suits your needs. As an added bonus we are generally able to ship right away on most products listed in our store! Aside from aesthetic variations of our many round stock tubes, you might also wish to consider their superb mechanical properties as well. That is after all the main reason we love carbon fiber so much! Of course it's an added bonus that it looks incredible too. 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.
