What you need to be careful of is how it reacts to resin, where its probable that epoxy will show some risks, polyester is more forgiving. I guess silk would come up with some attractive numbers, perhaps hemp too (No pun intended).
Reference manila rope for which hemp was widely used during WW2. Hemp cloth is quite widely researched and likely available as a product. I believe silk was investigated for composites in the 90s.

Im not really understanding this, since a turbocharger already has its hot side and cold side occupied. Perhaps what you are looking for is an exhaust driven alternator, or do you mean something rather smaller than existing APU?
