Source for cf shaft blanks

I don't think carbon fiber tubes are as finite a resource as desirable lumber. If memory serves, wood sources are what triggered that "rule," to begin with.
 
Sorry, not looking to shake the boat. I thought like j2pac that there was nothing rare about CF tube blanks and it was good to have reputable sources posted so people don't get scammed by random online shops.
 
Some us stock here and there but I believe there all coming from china, pick a bigger company if your planning to buy a lot. Cost Xtra but I sent them all the specs and taper length I wanted and they built them to it.

THe blanks Prathers sells is also nice
 
Several vendors, but they all probably originate from only a few factories in China.
Having said that, the technology itself isn't as advanced as you might think and I'm sure there are companies in other parts of the world that can build CF tubes. The biggest cost is having the mandrel made, but if you want to stand out from the crowd, you can certainly have your own taper made with the wall thickness you prefer.
In my experience the key factor is the QC in the factory, so the tubes you get sent are as straight as humanly possible, so finding someone who will do that for you and be cool if you reject a blank is important.
 
Speaking of blanks, Chris H mentions his are finished. I'm curious that that finish is. Some people say it means the sanding and polishing. In Chris's case I got the impression there was some type of finish on the cf. Anybody know?

Yes there is a coating on them so you don't see or feel the weave pattern. But even I do not know exactly what they coat them with.

I haven't seen a cf shaft that is woven. Woven cf is mostly used in applications where the expected forces are in many directions or are unpredictable, or it is used for lower manufacturing cost of semi complex designs. Woven cf is weaker than the biased lay-up that products like golf clubs, fishing rods, pool cues, and airplane parts use. You won't see a weave on a 777 wing (I can say with absolute certainty, I helped design the machinery that builds the wings).

What is the correct name for the pattern going through Carbon Fiber?

The only pattern I see in my CF blanks is a barely noticeable radial pattern, almost like curly maple. It is not a pattern of the CF fibers, but likely a relic of how they form the CF on the blank or how they clamp it. The pattern appears to mostly be in the resin binder.

The shaft blanks I have used seem to be completely unidirectional, longitudinal lay-up. In more advanced structures, layers are built with the fibers running on a specific bias depending on how the structure needs to resolve forces.

Okay.

Here is a pretty decent explanation from a bicycle manufacturer.

Unidirectional Versus Woven Carbon Fiber - Appleman Bicycles

Unidirectional Versus Woven Carbon Fiber Appleman Bicycles prioritizes strength, durability and using the right material for the job. That’s why I use unidirectional carbon fibers to build all of the structural tubing that goes into a custom bike + woven/braided carbon in the joints...

i've only seen these 'weave finish' shafts on j/b cues or lo-end players. never seen a decent play shaft made this way. every decent-to-good players have all been matte finish.
