ARRIS 12mm 10mm x 12mm x 500mm Roll Wrapped 100% Carbon Fiber Tube Matt Surface (2 PCS)

Yes it's true; I bought this to replace the axle in my garden cart. Honestly it wasn't much more expensive than steel, and it was the exact length and diameter I needed for the new wheels I bought. I did get stuck briefly when I realized I couldn't drill holes for the cotter pins on each end (breaks up the fibers and weakens the structure over time). So instead I used a tight rubber grommet surrounded by a hose clamp. Works great so far!

I purchased these Carbon Fiber tubes from Amazon to build a Multi Rotor aircraft in addition to using some 3D printed parts, and needed something strong and lightweight for the arms of the aircraft. So naturally I found what I was looking for on Amazon, once I got the carbon fiber tubes to my door I could tell these were true carbon fiber and that they were just what I needed to start working on my new Multi Rotor.I measured the CF tubes with my digital caliper and the diameter varies slightly from 12.4mm up to 12.7mm, which doesn't affect the applications I use the CF tubes with. I plan to order more of these CF tubes for some more Multi Rotor and Airplane builds.

Excellent quality matt surface carbon fiber tubes. Unit's dimensions were accurate (I verified using machinist micrometer), and tubes were true (straight).

True to size and beautiful. Super light and a tight, tight weave. Cuts very clean so the pre-preg cloth used had plenty of resin. Not your typical cheap stock. Will and have purchased again.

Not what I was looking for but excellent quality.
