Any materials anons out there? Can anyone tell me why carbon

they're hard to make

Could you elaborate? I don't want any detailed industrial manufacturing secrets.

I mean I don't get it. I just bought a roll of IM9 3K carbon fiber with epoxy sizing for my fishing rod making hobby. IM10 would have been available too as 6K. I have been looking at news about carbon nanotubes ever since I first heard about them like 20 years ago, but they haven't yet shown up as a product. I'd just like to know why is that so.

its just not cost effective at the moment, far to small a scale to be able to mass produce them effectively which drives up cost and all that.
I believe it is mainly because of the size of the part and not the actual material it is, everything just needs to be insanely precise

You are not telling anything about it. I would pay 50 grand and more for a useful roll for my fishing rods. I simply want the best stuff there is for my thing and the cost is the least of the matters. But it isn't simply happening.

They are extremely expensive to make and at the moment, next to impossible to make a significant amount of it flawlessly, one atom out of place and the whole tube becomes brittle and only has a fraction of its proper strength. I think the longest tube anyone has been able to make so far is a few metres and that is in a laboratory. It will be decades before you will see any sort of large-scale production involving carbon tube or sheets, and even then it will likely only be in high-end products like electronic chips never mind your fishing rods.
