Product Description

1.Product Description

Carbon fiber tube can be used to replace or substitute aluminium or steel tubes in a wide range of projects. Their superior mechanical properties mean that tubes of the same weight as an aluminium or steel tube can be much stronger, or that tubes of the same strength can be much lighter.

This tube is manufactured predominantly using high modulus (T700) unidirectional prepreg carbon fiber oriented to provide maximum strength in the lateral (length-ways) axis but the use of prepreg reinforcement oriented at 90° also ensures that the tube has good crush-strength; ideal for real-world applications.

The use of unidirectional fibers and maximum strength in the lateral axis does mean that the tube is not strong across its diameter as it is along its length so should be used in such a way as to avoid unnecessary crushing forces across the tube.

5.Technical Details

Roll Wrapping

The phrase "roll wrapped" refers to the process used to manufacture these tubes. The prepreg carbon fiber is first laid up around a mandrel in multiple layers. Once the reinforcement is in place it is spiral wrapped with heat-shrink tape (this is what gives roll-wrapped tubes their characteristic ribbed appearance) before the whole assembly is oven cured.

Roll wrapped carbon fiber tubes offer superior strength in general use to "pultruded" tubes (which have all their fibers running in exactly the same direction). This is because forces on a tube are rarely exclusively in straight compression or tension, whereby the unidirectional fibers of a pultruded tube are not ideal.

How to Cut and Shape
This carbon fiber tube can easily be cut and finished using simple workshop tools like a hacksaw and some wet-and-dry paper. Cutting and finishing a carbon fiber tube can also be perfectly safe if you follow some basic safety precautions.

Mechanical Properties & Specification

Our roll wrapped carbon fiber tubes are manufactured from special high-modulus Toray T700 unidirectional prepreg carbon fiber oriented at 0° (down the length of the tube). Crush/burst strength is provided by unidirectional E-Glass oriented at 90° (around the section of the tube).

---------- FAQ ----------
 

1.How Do Prepare The carbon Surface For Painting?
Many people prefer the natural finish of these carbon products, however if you wish to paint them for your specific application then you can do so. A light key with a fine abrasive paper like a 1200 grit wet and dry paper and a thorough degrease and clean using milddetergent or an alcohol wipe should be all that is needed to prepare the surface for paint.

2.What is The Maximum Torsional strength of This Tube/Max Torque Until it Yields? Could it Be Used (With Modifications) For A Motorsport Driveshaft?
We don't have figures for the torsiona/strength of our roll wrapped carbon fiber tubes because they're not really designed for torsional load applications. These figures would be calculable (from the layup schedule and the fiber properties) but it's very involved work. Tubes designed for torsional load, like a prop-shaft or steering column, would normally make extensive use of +/-45° (or similar) fiber orientation because 0 or 90° fiber orientation means that the torsional load would try to shear the tube. f you wanted to 'adapt" a roll wrapped tube like this to improve its torsional load capabilities then laminating some lavers of our Carbon fiber Braided Sleeve would add significant +/-45° fiber orientation and so torsional strength. 

3.Is It Possible To Cut A Thread Into Your Carbon fiber Rods And Tubes?
Unfortunately it is not possible to cut a usable thread into carbon fiber composites. The nature of the material is such that the teeth on a thread would not be able to take any load and would break up either during thread turning or the first attempt at using the thread.
Where it is desirable to have a threaded method of attaching the tube or rod, it is commonplace to fabricate and then bond an aluminium insert into the tube or over the rod end which can then have a thread cut into it.

4.Are Lengths Available Greater Than 2.5m?
No, the maximum length available for our standard roll wrapped tubes is 2.5m. Our woven finish roll wrapped tubes are avalilable in lengths up to 2m , Unfortunately we can't supply tubes in lengths longer than those listed on the website.

5.Are Any Other Thicknesses Available?
Unfortunately not. Our roll wrapped tubes are only available in the listed wall thickness and diameters.

6.What ls The Maximum Service Temperature of The Roll Wrapped Carbon Tubes?
The maximum service temperature of the Roll Wrapped Carbon fiber tubes is 80°c

7.How Straight Are These Tubes?
There is no manufacturers tolerance for the straightness of these tubes due to the method of manufacture. As such they are not available to any specific set tolerance in terms of straightness. However if you have a specialist reguirement or use for these tubes please get in contact and we can measure the current stock to see if they meet with your reguirements.
