Does anyone know where to get the carbon tubes I've seen on some RRP poles?
Don't think Rick Roy does them?

Super Jet RRP Pole - carbon tubes?

Not sure anyone makes actual carbon fiber tubes, but I make a vinyl wrap for the RRP tubes, and I wrapped mine with Carbon Vinyl:

Thrust Innovations has the "look alike" carbon tubes, not actually carbon, but it def looks like it...check out their website

No one said the thrust tubes were actual carbon, they're anodized. Carbon fiber tubes wouldnt be strong enough anyways, and if someone made a set that we're, they'd be heavier then the aluminum tubes.

yeah! the two aluminum tubes is not the reason for the weight of the pole and would not make any $$ sense to make them in carbon.

LOL...carbon fiber has a higher strength to weight ratio. That's why racing sailboats have carbon fiber masts and not aluminum. RRP made the pole out of aluminum because it was cheaper so they can make a profit. Not because they would be heavier than aluminum.
LOL. You thought graphite was weaker than aluminum? Carbon fiber is far stronger than aluminum and is much lighter weight as lilracer94 said. It's a tensile strength of 500ksi for carbon fiber versus 65ksi for aluminum. So in essence, you could have a RRP style pole that could be over 7.5x lighter weight wise, but have the same strength. Course, you have the cost issue unless your laying it up yourself.

Thrusts pole tubes looks nice, holding an aluminum tube I doubt its worth the money to find someone to build you carbon tubes. Whatever floats your boat. would be cool! If your set on the actual carbon look, Derricks wrap looks like the real mcCoy. But idk of anyone who makes carbon tubes already

For me I just couldn't justify the cost of a set of tubes made properly. Anybody have a clue on price for a nice set? Can they be vacuum bagged to really make it worth while? And they would also be an upgrade to an already purchased rrp pole. The whole set up may be a bit spendy. I would think a carbon pole from Tem would be every bit as good if not better. Just my random .02 Unfortunately Tem's pole (I think, but not sure) only works on the sf's.

they would need to be extruded. it's an expensive process. making quality CF tubing is not something you can do in your garage with a mold and a vacuum pump.
I can probably supply these Jim, however although carbon will always be stronger than aluminium for a given wall thickness it may be worth considering that in the event of a failure (and everything will at some point) aluminium is likely to bend and buckle but carbon more likely to shatter particularly on impact and leave nasty sharp bits to impale yourself on. All in all I don't think its worth the small amount you will save in weight but it would look cool.

Tensile strength is not the issue, and is essentially irrelevant for handlepole tubes. The increased stiffness and lack of plasticity of carbon are a big deal however. Add in the increased fracture risk around stress concentrators, and somebody is going to end up getting impaled...
Here's a relevant study...and even in this study they are comparing CF reinforced polymer tubes, not pure CF:

In the study they were testing a carbon fiber tube made of 2x2 twill weave with 4 wraps on it. 2x2 twill weave is never used for structural applications, rather it is used for visual appeal. Thanks for posting the link, very informative. It would be interesting to see the same test done with a CF tube with a more intricate weave. Perhaps something like this on a larger scale. This is a homemade winding machine.

At least part of the purpose of that study was to determine if those tubes were suitable for intrusion protection bars in car doors...so I'm surprised they used a "cosmetic" type of layup. I didn't catch that, thanks for pointing it out. Wonder if the polymer part of the tubes steered them in that direction for some reason?

go kevlar..carbon is too brittle... actually the pros make a combination of materials so its light and does not break...

Not going to read this entire thread, BUT, I have never seen a set of alum tubes break and they weigh nothing. ALSO, and a BIG point here, Aluminum and carbon are not a good combo, weather it be cast or billet alum, the carbon will react BADLY as in serious corrosion against the aluminum.
The carbonised tubes offered by Thrust give a nice look and are far less expensive than having a carbon tube made in the odd size that is required.
BTW, Carbon fiber vrs Aluminum strenght to weight I would have to believe if the correct carbon and resin ratio and types were used the carbon would be stronger. But finding the right person to manufacture the carbon tubes correctly would be a chore.
