How to Choose the Perfect Carbon Fiber Tubes
#1 Length & Diameter
1 / 5
Our roll-wrapped carbon fiber tubes are crafted from multiple layers of UD (unidirectional) carbon fiber in the middle, and 3K weave carbon fiber fabric for outside, which are rolled onto the axial mold. Hence, the thickness of the carbon fiber tube is determined by the quantity of layers of the inner unidirectional carbon fiber. So any thickness, diameter, and length can be customized according to your requirement.
- Outer Diameter (OD): 1.8mm (min.) - 300mm (max.)
- Inner Diameter (ID): 1mm (min.) - 280mm (max.)
- Length: 50mm (min.) - 4000mm (max.)
#2 Weave
2 / 5
You can choose from several weave options for the outermost layer to meet your mechanical requirements while also giving the carbon fiber tubes an attractive appearance.
- Twill Weave
- Plain Weave
- UD (Unidirectional)
#3 Surface Finishing
3 / 5
It also comes in various finishes, including glossy and matte. Glossy carbon fiber has a smooth, reflective surface, adding a sleek and shiny appearance. Matte carbon fiber has a non-reflective surface with a softer, subdued finish.
- Glossy
- Semi-Matte
- Matte
#4 Carbon Fiber Tows
4 / 5
“K” represents one thousand and is used to indicate the number of fibers in each bundle. The larger the number, the wider the bundle, which also results in differences in appearance.
- 1K
- 3K (Most Common)
- 6K
- 12K
#5 Carbon Fiber Strength Grade
5 / 5
We understand that different applications demand different levels of performance. That’s why we offer 3 of the most popular carbon fiber grades to meet your specific needs
- T300 (Most Common)
- T700
- T800

Frequently Asked Questions about Carbon Fiber Tubes
FAQ
1. What dimensions are available for carbon fiber sheets?
Square carbon fiber tube: Maximum 300x280x6000mm
Circular carbon fiber tube: Maximum OD300xID280x6000mm
Any sizes can be customized that smaller than the maximum length and size
2. What shapes of carbon fiber tubes do you manufacture?
Sinofibre provide premier carbon fiber tubes in multiple shapes that include:
- Circular carbon fiber tube
- Square carbon fiber tube
- Rectangle carbon fiber tube
- Tapered carbon fiber tubes
3. Do you offer free samples before bulk orders?
Yes, the FREE sample can be provided for testing in standard sizes. However, the nominal sample cost will be charged if customs sizes, and these costs will be refunded when you place the bulk order.
4. Can our logo be displayed on the surface of carbon fiber sheets?
Certainly. We offer 5 methods to display your logo on the surface:
- UV printing
- Screen printing
- Enamel paint
- Laser engraving
- CNC engraving
5. What “K” carbon fiber types do you offer?
3K and unidirectional is the most common use for carbon fiber circular tubes and square tubes, any other grade also available, like 1K, 1.5K, 6K, 12K etc.
6. Do you provide pultrusion tubes or roll wrapped tubes?
We offer both pultrusion tubes and roll wrapped tubes. But generally roll wrapped tubes would be preferred as it’s made up from several piles of prepreg carbon fiber, and the orientations can be adjusted to reach the the property that you required. And strength and durability the roll wrapped tube is going to be more versatile.
However, the roll wrapped tube also has disadvantage, that is mandrel dictates the maximum length that it can be made, unlike pultrusion tubes that can be made infinitely long.
7. What weave patterns are available?

3K + 45° UD + 90° UD + 3K
20. How can I cut carbon fiber tubes in house?
Our carbon fiber tubes can be cut by a normal circular saw easily, but for the more suitable and precise parts. Better machine the sheets on a CNC lathe.
21. Why are the carbon fiber tubes so expensive?
We made 2 primary reasons for this:
The premium raw materials are expensive, such as Carbon fiber filament, Epoxy resin.
Unlike other manufacturing processes, the production of carbon fiber sheets are mainly process by skilled composite technician, and there is no machine that can replace the manual lay up the carbon fiber so far.
22. Can carbon fiber tubes be painted?
It depends on your applications. Actually the resin we used is UV resistant, so the extra anti-UV paint is not so necessary.
However, varnish can be painted on the surface if you want a more glossy surface.
But, we have the Mirror surface for your selection, which is much more glossy than the standard, the price is a little more expensive, but it’s definitely much cheaper than the varnish process, and more eco friendly.
23.Can I have the datasheets of the carbon fiber tues?
Sure, the datasheets of carbon fiber filament, epoxy resin, carbon fiber tubes, all the raw material testing report can be provided.
