Carbon fiber pipe are widely used as the basic material for Light Aircraft Tubing, aerospace, defence, leisure, automotive ptubeucts, industry and the medical sector as well as other applications includes building construction repair and is finished with a wrap of 3K, 6K, 12Ktwill or plain, Glossy surface or matte surface, and a variety of surface can be customized


Selling Points


Carbon fiber tubes have incredible linear strength due to the orientation of the carbon fibers and are used in a variety of applications. (Compared to conventional structural metals (such as steel, aluminum and stainless steel), carbon fiber tubes deliver excellent tensile strength characteristics. Besides exhibiting outstanding strength, our composite carbon fiber tube is durable, lightweight and extremely rigid.



1. Made of high modulus 100% carbon fiber with epoxy resin
2. Great replacement for the low-grade aluminum wing tubes
3. Weights only 1/5 of steel and 5 times stronger than steel
4. Low Coefficiency Of Thermal Expansion, High-Temperature Resistance
5. Good Tenacity, Good Toughness, Low Coefficiency Of Thermal Expansion



1. Aerospace, Helicopters Model Drone, UAV, FPV, RC Model Parts
2. Manufacture Fixtures And Tooling, Industrial Automation
3. Sports Equipment, Musical Instruments, Medical Device
4. Building Construction Repair And Strengthening
5. Car Interior Decoration Parts, Art Products
6. Others

Carbon Fiber Tube Manufacturing Process :

4-Axis braiding is a process in which we braid carbon fibers over a mandrel. The braiding machine stays in one place and an aluminum mandrel traverses inside of the braiding hoop. The layer of braid is then wet-out with epoxy resin at a 2nd stage in the machine. The laminate is then consolidated and cured at 280F.


Braided composite structures offer extreme durability and toughness due to the interlocking fibers and no seams.
If damage does occur, it does not tend to propagate within the structure.

Typically braided carbon tubes have approximately 75% of fibers directly on the axis of the tube. These fibers are continuous fibers from one end of the part to the other. 10 % of the fibers are +/- 45 deg and around 15% are 90 deg (hoop)
We can make some adjustments to the percentages of fiber orientation; however, it is not possible to get high percentages of +/- 45 deg.

The inherent high percentage of fiber on the 0 axis makes a braided tube a very good compression or bending tube.
Because the machine stays in one place and the mandrel traverses, there is no length limitation to the parts that can be built (the building length, oven length, and mandrel lengths are limiting factors, but the process itself is not limited).

We typically braid longer length parts or larger manufacturing runs compared to pre-preg

Braided carbon fiber tubes tend to have more surface ripples and small voids in the laminate. This is not a structural issue but it can be a cosmetic issue and it may have an effect on the OD tolerance of the part.

Examples of some applications for braided tubing

Communications towers, large antenna assemblies, portable antennas, drone wing spars, aircraft structural tubing, sailboat spars, truss tubing, reinforcing tubes, spacer tubes, stiffening tubes, compression struts, GPS towers, high tension cable struts, awning support tubes, structural beams, low interference towers.
