carbon fiber square tubes

Carbon fiber square tube also named braided carbon fiber square tube is manufactured compression molding process. Jinjiuyi carbon fiber team offers square rectangle hexagonal octagonal carbon fiber tubing in various size for different applications. Our square carbon fiber tubes are available in various dimensions and lengths, we also offer custom thicknesses, sizes, and lengths.

Product Description

Jinjiuyi’s Square Carbon Fiber Tubes are laminated from prepreg high-strength carbon fibers and epoxy resin, the shape of the tubes is square with rounded corners. Upon request, the inner roll wrapped high strength, medium modulus unidirectional carbon fiber prepreg, Fibers oriented at 90 degrees (hoop) are wrapped around the circumference to provide high crushing strength and stiffness, same with our round tubes. Usually, the outer warped 3K finish carbon fiber weave oriented in a 0/90 degree orientation and cured at high temperatures and pressure. Unlike metal tubing, this type of construction offers a high stiffness to weight ratio tube with increased bending stiffness and axial strength, a high crush resistance and tight inner diameter (ID) tolerances. Our square carbon fiber composit tubes have an outermost layer of twill or plain fabric which gives the tubes a few advantages including better machinability, reduced splintering, and the decorative aesthetics associated with carbon fiber.
