▎ 摘　　要

NOVELTY - A carbon foam is formed by providing a carbon source; blending the carbon source with a solvent to form a mixture; heating the mixture at atmospheric pressure and in a non-oxidizing atmosphere to produce a carbon foam precursor and a solvent mixture with extracted volatiles; and heating the precursor at atmospheric pressure to form a carbon foam. USE - Formation of carbon foam used for composite carbon foam (claimed). ADVANTAGE - The method provides low-cost methods of producing a carbon foam through a partial solvent extraction process and sintering process, and/or traditional foaming at atmospheric pressure. The method includes increasing carbon foam strength through the addition of carbon fiber filaments or tows into the carbon foam. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) forming a composite carbon foam which involves producing a first carbon foam precursor from a mixture that includes a carbon source and a solvent; grinding the first carbon foam precursor into a powder, where the powder includes an average particle size of at least 50 nm; adding a carbon fiber or carbon fiber tows to the first carbon foam precursor; and heating the first carbon foam precursor and the carbon fiber or carbon fiber tows at atmospheric pressure to form a composite carbon foam; and (2) composite carbon foam comprising a carbon foam disposed within a graphene, a graphene oxide, or a graphite outer layer.
