There is a French epoxy foam that is weighed carefully, mixed then goes off while making bubbles hopefully filling your mold or space between CF panels perfectly, before hardening.
Paul Bieker uses this in CF hydrofoils that he builds for Bora Gulari and a few others: they are only about $1000 each.
This foam is available in France, UK and Oz and is unavailable in the USA.
