Description: Size and Shape: pultrusion rounded tube with 4mm outside diameter, 2mm inner diameter, 420mm overall length. Pultrusion: pultruded tube means that all the fibers are in one direction, which makes it stronger than the woven tube in tension. Lightweight: strong as metal but only one-fifth in weight, corrosion-resistant, and heat-resisting. Smooth Surface: made of high tensile and modulus unidirectional carbon fiber. Application: pultruded carbon fiber tube is used for racing drones, RC helicopter wing, RC airplanes and RC sailboats, kite spars. Features:Tube Shape: Circular PipeOutside Diameter: 4mmInner Diameter: 2mmOverall Length: 420mmPackage Content:8 x Carbon Fiber Tube
