I bought a bunch of this, if anyone has any interest in it. Not exactly easy, but it can yield very cool results. Shoot me a PM if interested at $50 / yard, shipping from the US.
Prepreg - 3k 2x2 Twill Carbon Fiber Prepreg Fabric with Epoxy Resin
Out-of-autoclave prepreg carbon fiber fabric for making small or large parts. This is an uncured prepreg material and requires an oven or autoclave to cure it. It can be cured at 250F. A small toaster oven or conventional oven works great for small parts. A DIY oven can be made for large parts. Make your own high quality carbon fiber parts.
This material must stay frozen or it will cure and become brittle. Make sure you have a freezer big enough or plan to use it within 20 days. The colder you keep it, the longer it will last. You could cut it to smaller pieces and store in conventional freezer.

Fully Compatible:
High temp epoxy hand-layup molds
Carbon or glass fibre prepreg molds
Epoxy tooling board (high temp)
Aluminium / stainless steel molds
Toughened glass (for flat sheet/panels)
Storage and Handling
When not in use, prepregs should be kept frozen at -18°C (0°F) in sealed plastic packaging. When ready to use, the material should be removed from the freezer and allowed to thaw fully to room temperature before being removed from the packaging.
Remaining material should be re-sealed before returning to the freezer to avoid the risk of moisture uptake.
Cure cycle:
1 hour ramp to 80C
1 hour dwell at 135C
40 minutes at 140C
30 minutes at 150C
1 hour ramp down to 130C
heat off cool down
