Our Carbon Fiber Solid Rectangular Rods are manufactured by a pulling continuous carbon fibers combined with a resin matrix through a heated steel forming die. This process is referred to as pultrusion and is used for producing continuous lengths of composite materials with constant cross-sections.
As the carbon fibers are saturated with the resin mixture and then pulled through a rectangular die, the hardening of the resin is initiated by the heat from the die and a rigid, cured structure 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 rod with a very low coefficient of expansion. This type of construction offers a high stiffness to weight ratio rod with incredible linear strength, due to the orientation of the carbon fibers, and tight outer diameter (OD) tolerances.
Our Carbon Fiber Solid Rectangular Rods have a matte finish surface and are available in various sizes.
