I'm reading more and more articles about carbon
nanotubes. The most recent being an article
about their use in reinforcing the binding resin
in carbon fiber.

Not one article has discussed health issues.
I know first hand that the human body can
get rid of fiberglass fibers. Scratch enough
and your skin will blister and shed the material.

So what happens when the fiber are nano-scale
and can penetrate individual cells? How does
the human body get rid of them?

What are the long term effects?

Fiberglass is almost pure silicon. I don't see a problem.




I'm Horvath and I approve of this post.

Interesting idea; what's the benefit of nanotubes over short strands
of plain ol' carbon fiber?

Yeah, but that doesn't mean your skin grows back at 100% of original
condition afterwards.

Don't know about nano-scale effects, but I can tell you that carbon
fiber makes wicked splinters.

You mean a space elevator? That'd be cool. I was recently rereading
Clarke's "Fountains of Paradise" coincidentally.

Amazing that he and other sci-fi writers thought so far in advance. Great
book...

Any sort of fiber that thicken resin and fills the
voids in the resin will increase strength. But if
you want to keep the resin thin, it seems carbon
nanotubes--being so small work best.
