Jinjiuyi offers a wide range of carbon fiber tubes for different applications. Our main products are rolled wrapped round carbon fiber tubes, square carbon fiber tubes, carbon fiber rods, carbon fiber poles, carbon fiber flat materials, carbon fiber heterogeneous materials, glass fiber tubes, glass fiber rods, and so on. We wholesale carbon fiber tubes which are producing by our own factory, giving us complete control over the characteristics and quality. If you’re replacing an existing metal tube, a good way is with a similar dimensions carbon fiber tube. Jinjiuyi carbon fiber team will give you some suggestions and steer you down the right path.
Our roll wrapped carbon fiber tubes are made of multi-layer unidirectional carbon fiber and 3K weave carbon fiber fabric rolled on the axis mold. The thickness of carbon fiber tube depends on the number of layers of the inner unidirectional carbon fiber. The surface texture of the carbon tube is generally 3K twill or plain weave, gloss or matte finish can be chosen freely, the 3k fabric weave that gives carbon fiber tubes their traditional ”carbon fiber look” is only the outside layer and helps with durability. Unidirectional carbon fiber and fiberglass can also be used as the surface of the tubes, such fiberglass tubes can be many different amazing colors. We usually manufacturing T300 carbon fiber tubes with standard modulus.
Our high strength square carbon fiber tubing is fabricated with unidirectional (UD) carbon fiber prepreg, the unidirectional layers are wrapped around a mandrel and oriented in a 0/90 degree orientation and cured at high temperatures and pressure. The outermost layer is 3K twill or plain fabric which gives the square tubes beautiful carbon fiber exterior. A variety of types or grades of carbon fiber tubing are available, as well as various exterior materials. 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 tubing is also significantly lighter than pultruded tubing.
Our carbon fiber pultruded tubes are made by pulled fibers through a shaped die while simultaneously injected with resin to create the required profile. 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. Pultruded carbon tubes are perfect for applications of bending and pulling as the carbon fibers oriented along the length of the rod.
These pultruded carbon fiber rods are great for reinforcing structures, use them alone or as reinforcements for foam or balsa structures. Due to different processing techniques，The straightness of pultruded CFRP tubes worse than the roll wrap carbon tubes. So we do not recommend pultruded carbon tubing or rod in use for drone or UAV motor arms.
We offer pultruded carbon fiber tubing in a variety of outer diameters from 0.6mm to 100mm, the length can be customized.
Even Jinjiuyi is a carbon fiber tube factory, we do not really “stock” carbon tubes in warehouse. There are too many different wall thicknesses and lengths options that most carbon fiber tube is custom built for the application. What we do consider stock is carbon fiber tubing sizes that we already have a mandrel for (tooling). When you purchase carbon fiber tubes, we can quickly delivery the tubes in 7-10 days. Jinjiuyi always offers custom-make carbon fiber tubes services, if you need large diameter carbon fiber tubes or super length carbon tubes, we can customize them according to your size. The maximum diameter of our carbon fiber large tubes up to 60mm.
As a professional carbon fiber tube supplier, we did not listed all the products here, so hope you can tell us your project details including ID, OD, length, dimensional tolerances, quantity, structural requirements, surface finish, surface pattern, material (if you know), temperature requirements, processing technology, etc.
