I was thinking of making a mockup out of something bendy, and casting a male and female mould. Then I could squash the carbon between them both.
Your part might be suitable for that method but generally speaking I wouldn't do that. I did try that method once and the results weren't very good, I ended up with voids and lots of slippage between the layers of cloth (although that would depend on geometry). IMO, female mold with bladder, or male mold with vacuum bag is a much better method.
