Round Solid Carbon fiber rods utilizing advanced Nano technology. These lightweight pur carbon fiber rods are round solid carbon rods that are light weight and flexible yet extremely strong. Round carbon fibre rod made of 100% carbon fiber with a flat finish, Rods are made from 3K Tow carbon fiber weave, this means each weave group consists of 3000 carbon nano tubes. These rods can have any number of uses including RC cars and planes, projects requiring high strength to weight ratios, drones and more. Carbon fiber may also sometimes be referred to as Carbon Fibre, riber tubes, airplane tube, Carbon 6, raw carbon, carbon x, pur carbon, carbon fiberglass and fibra de carbona just in case you are not sure.
