– Carbon Fiber Tube - 8mm X 6mm x 1000mm – Pultruded Round Hollow Carbon Fiber rods Black Matte Finish - Pure Carbon Fibre Hollow Tube shafts - for RC Planes-Drones, Boat DIY Craft Projects

Good

Nice carbon fiber rods. The inner and outer diameters are accurate along the whole length. They are good and strong.

Bought the 10 pack with plans to make a batch of Amtgard bats, made a prototype with a solid wood handle and it broke at the stress point created by the handle while blocking a shot in the third fight in the bear pit tournament I was in at the time.

I received two (2) 8mm x 6mm x 1000mm pultruded tubes from KARBXON November 5th, 2025 after extensive shipping delays and both tubes are warped over 4mm over their lengths—a horrible defect for pultrusion manufacturing. This is manufacturing defect and I was sold “factory seconds” as in, defective parts, instead of arrow-straight, perfectly formed tubes as pultrusions should always be. The only other way for a pultrusion to warp so dramatically is compression damage or radical temperature differential after manufacturing. They’re not damaged. They’re manufactured wrong and I will be seeking a replacement one time, then full refund if this company and seller cannot deliver a correctly made pultrusion that is actually straight. CM Update 11/7/25, well today UPS brought me two more orders (of four, each) of the 8x6x1000mm size in perfectly unscathed boxes, and that now makes 10 for 10 badly warped pultruded tubes. This should not be happening with such a robust pipe diameter. Perhaps the seller will respond here. Shame, I really needed a reliable supplier for metric pultruded carbon but I’m being sent totally warped waste stock—strong and dimensionally accurate, but another 100$ badly warped order going back.

don't expect this to be as strong as a woven carbon fiber tube, more like the strength of a dowel

Strong and light
