This would very much depend on what kind of level of flexibility and perhaps "breathability"you would like in this "carbonfibre-look" outer layer.
I made a set of custom footie "shin-pads/protectors" from one layer of Twaron outer- and two layers of kevlar -- I laminated this with EC's flexible Resin, for the first pair, and actually found it to be too soft and flexible.... I added an inner layer of pure heavy kevlar cloth, and that did the trick.. My daughter now has the coolest set of shin-protectors on her football team ..

I do not think you could make softer fabrics from the normal reinforcement fabrics used in composites, but something like a pure black Diolene or Diolene and Twaron mix (if that exists) might be usable.. Dyneema works very well, and is soft and very strong. but the sort I have is shiny white satin weave....
