4mm (3mm) Pultruded Carbon Fibre Tube 

Pultruded carbon fibre tube with a 4mm OD and 3mm ID (0.5mm wall thickness). This precision made carbon fibre tube is suited to lightweight applications in radio controlled models, electronics, robotics and similar. The tube is manufactured to tight tolerances using high strength carbon fibre and an epoxy resin matrix for maximum performance.

Available in 1m and 2m lengths.

Pultruded carbon fibre round tube manufactured from 100% unidirectional carbon fibre.

The tube has an outer diameter (OD) of 4mm and a wall thickness of 0.5mm leaving an inner diameter (ID) of 3mm.

Typical Uses

This 0.5mm thick, small 4mm OD tube is ideally suited for use in radio controlled (RC) aircraft, helicopters, U.A.V's and other models but would be equally suited to other precision applications like robotics and automation.

Pultrusion Explained

Pultruded tubes are the most commonly used type of carbon fibre tube. Pultrusion is a method of manufacturing continuous lengths of fibre reinforced section (in this case tube) by pulling continuous strands of carbon fibre through resin and a former before curing the resin all in one process.

Pultruded tubes feature 100% longitudinal fibre orientation which gives them excellent strength along their length but does make them vulnerable to crushing forces. For applications where none-uniform forces are likely to be encountered, including crushing forces, roll wrapped carbon fibre tubes should be considered as an alternative.

The pultrusion process allows incredible tiny diameter tubes to be produced (as small as 2mm OD).

How to Buy

Our pultruded tubes are available in a 1m or 2m length. Please choose the length you require from the drop-down list.

Discounts are available for larger quantities and wholesale/trade purchases; please contact us for details.

Further Information

How to Cut and Shape

This carbon fibre 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 fibre tube can also be perfectly safe if you follow some basic safety precautions.

For a comprehensive guide to both safety advice and cutting and finishing techniques watch our video guide to cutting and shaping carbon fibre sheet and carbon fibre parts.

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 mild detergent or an alcohol wipe should be all that is needed to prepare the surface for paint.

Generally, the pultrusions are used ‘as-is’ and don’t require painting. If you really do need/want to paint the pultrusions then a light key with a fine abrasive paper like a 1200 grit wet and dry paper and a thorough degrease and clean using mild detergent or an alcohol wipe should be all that is needed to prepare the surface for paint.

No these pultrusions are not magnetic.

No, this pultrusion is manufactured from standard modulus fibres.

We do not currently offer a custom cutting service for our tubes and pultrusions. However, they are able to be cut DIY relatively easily as you can see from our tutorial video: How to Cut Carbon Fibre Sheet, Tube and Parts

Unfortunately it is not possible to cut a usable thread into carbon fibre 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.

In simple terms these carbon rods would work with linear bearings in that fashion. The only concern is long term durability as the carbon surface is not quite as hard as aluminium and thus would likely wear quicker in many circumstances. For low usage or low load situations this may well not be a limiting factor.

The HDT of these pultrusions is 80 °C.

Yes absolutely! If done carefully, a hacksaw can be used to cut a pultrusion. Take a look at this VIDEO where we show various methods of cutting carbon fibre.
