Excellent Strength and Stiffness Standard Modulus Round Carbon Fiber Tube
Standard modulus carbon fiber (SM) is the most common grade of carbon fiber used for our carbon fiber tubing. Standard modulus offers excellent strength and stiffness. It is 1.5X stiffer than aluminum and is the most economical grade.
This round carbon fiber tubing is fabricated with multiple layers of high-strength unidirectional carbon fiber prepreg and has a 3K 2×2 twill fabric on the exterior.
This round tubing is comprised of Carbon Fiber Braid and Unidirectional Fabrics. This product is ideal for building lightweight frames and structures. Our Carbon Fiber round tubing has been engineered to be much stronger under torsional and side loading than pultruded tubing. Our tubing is also significantly lighter than pultruded tubing. Our carbon fiber round tube has been designed so that the unidirectional layers are captured in a sandwich structure, eliminating longitudinal cracking and splitting. Two options for finish on this tube are available. Natural, where the finish shows the texture of the carbon fiber braid with a wet shiny appearance and gloss, which has a flatter, more uniform glossy surface.
As the carbon fibers are saturated with the resin mixture and then pulled through a die, the hardening of the resin is initiated by the heat from the die, and a rigid, cured tube is formed in the shape and size of the die. The majority of the fibers are running in the 0-degree direction, along the length of the tube, to produce an extremely stiff and lightweight tube with a very low coefficient of expansion. This type of construction offers a high stiffness-to-weight ratio tube with incredible linear strength, due to the orientation of the carbon fibers, and tight outer diameter (OD) tolerances.
