I believe aerohead has used a concrete female form to make aerocaps (or something).
deHavilland Aircraft Company used a concrete sarcophagus lower tool to receive steamed and glued plywood veneer laminations, captured below an airtight, heated, inflatable rubber 'upper mold' lid.
They could create half of the Mosquito bomber fuselage as a single composite component. Elegant!
