I wouldn't use carbon fibre as the sole material in a frame.

There was a thread about using it in different robot applications, about a year ago. I noted then that if you scratch something made of carbon, even cosmetically, you can cause it to catastrophically fail, with no warning like with metals that will bend.

Seeing as a frame is probably going to get the hell scratched out of it, that doesn't sound too appealing to me.

It's not an easy material to work with either. It can be very hazardous to your health if you don't have a good understanding of what you're doing and take safety precautions.
