How to Cut Carbon Fiber Tubes

Cutting Carbon Fiber tubes

There are a lot of things to consider when cutting carbon fiber tubes: cutting tools, finishing materials, PPE, dust collection, etc.
Dust collection is the major concern. Particles and dust generated while cutting carbon fiber tubes can be relatively dangerous
if proper care is not taken. Like many other fine particulates, in the right condition, carbon dust can be explosive.
Proper dust collection will greatly reduce this risk.

Also, take care around electronics; the conductive nature of carbon can easily fry nearby computers, laptops, and other devices. 

With this in mind, ensure proper precaution is taken prior to making your first cut. It may be worth covering or moving any devices in the area.

Cutting carbon fiber tubing can be difficult. If done incorrectly, the tube can be damaged beyond repair in the blink of an eye.

This article will break down the steps on how to cut carbon fiber tubes.

Materials Needed:

1. PPE: Safety glasses, dust collection, hearing & respiratory protection.

2. Cutting: Diamond coated abrasive cut-off blade.

3. Finishing: Sand paper or other abrasive surfaces

Cutting Carbon Fiber Tubes:

There are many ways to cut carbon fiber tubing. Whether you use a chop saw, tile saw, or hand held cutting tool,

follow these simple steps to assure a clean cut every time.

Choose the right blade for the job:
This is the most important part.When cutting composites,it is ideal to use a diamond coated abrasive cut-off blade rather than a toothed blade.
Teeth can catch the fibers and tear the material resulting in splintering or delamination.
Thicker tubes may generate enough heat to re-activate the epoxy causing the blade to “gum-up”.
To prevent “gumming”, cool the cutting surface/blade.Using a segmented blade will help reduce heat.
Another option is to actively cool by using a wet saw.
Choose the right blade for the job
Support the tube:
Supporting/bracing the tube (properly) is crucial to achieve a clean cut.To ensure a square cut,
brace the tube against a straight edge or dam that is the proper angle you desire.
An unsupported tube can result in a “burred” edge. This is caused by one side of the tube moving before the cut is finished.
Burrs are typically found on the “drop” section. If multiple sections are being cut out of a tube,
it is crucial to support and brace both the cut end and the drop end of the tube.
Supporting/bracing the tube (properly) is crucial to achieve a clean cut.
Clean the edge:
The cut edge may have burrs and/or fibers remaining on the tube. To clean-up the edge,
spin the cute edge on a piece of sand paper or other abrasive materials.
