Would there be advantages to a tensile biocomposite with Starlite and/or Firepaste e.g. as a coating or blended?

Can Starlite be used as heat shielding for [biocomposite] civilian rockets, and how would the reentry emissions differ?

You're aware that capsules commonly use cork as ablative heat shielding, right?

If you want to be better, you'd need something like the shuttle to get by without ablatives.

Cork is one layer of some heat shields (and a sustainable insulator)

This is how the industry failed and bought steel instead.

Guessing mach-whatever reentry speeds would strip it, shred it.
