An article for tooling composite materials, including a carbon foam, a sealant attached to the carbon foam so as to form a monolithic fine-grain graphite-like surface; and a skin of face sheet materials. The face sheet materials include: a spray-deposited coating of metal; more preferably, a thermal or plasma spray-deposited metal; and most preferably, a plasma sprayed Invar metal. The face sheet materials may optionally include a flash coating. The face sheet materials alternately include plastics, resinous materials and carbon-carbon composite materials. |
