Product Description

High-Performance Carbon Fibres 100% 3K Carbon Fibre Square Tube

Square tubes, also known as carbon fiber box sections, are optimized for high-performance strength and stiffness. With in-built radiused corners and flat sides, they are ideal for building support systems, lightweight frames, and structures.


Surface Finishes

Designed to make your composites corrosion resistant, UV protection and aesthetically pleasing, LIJIN provides finishes sustaining the long-term appearance of composite products.


Square tubes engineered for maximum strength and stiffness, or to satisfy application-specific engineering parameters. We specialize in making square tubes using pre-preg carbon fibre with epoxy resin and have a large range of tooling available. Therefore Laminated from prepreg carbon fibres and epoxy resin, our square tubes are made for applications requiring high strength and rigidity.

  • High-tensile and torsional strength to low-weight ratio
  • Excellent fatigue resistance
  • Dimensional stability
  • Easy to use in a variety of applications

Why Choose Us?

*Extensive experience of more than 10+ years
* Professional manufacturer
* Quality materials
* Expert and hard-working workers
* Strict quality control
* High quality is guaranteed
* Reasonable price


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 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.
