Carbon fiber comparison
Mtnflyer,FWIW, the above comments are accurate. That said carbon fiber is much stiffer(lb for lb) than glass. This is only an advantage if you have the engineering perspective to apply it effectively. Otherwise you will find it more difficult to form sharp curves, be equal in weight and more stiffness than required.
Regarding safety, epoxy is epoxy. Glass and carbon are particulates you don't want in your lungs. They are not the same hazard as abestos. Research the net for the difference if you are concerned.
I have enjoyed outstanding results with carbon. Send me your email if you want pics.
