1. A columnar-carbon and graphene-plate lattice composite material comprising:
a first single layer graphene sheet forming a bottom plate;
a second single layer graphene sheet forming a top plate; and
a plurality of fullerene-derived carbon columns positioned on the first graphene sheet, wherein the second graphene sheet is positioned on top of the plurality of fullerene-derived carbon columns, wherein the first graphene sheet, the second graphene sheet, and the plurality of fullerene-derived carbon columns form the columnar-carbon and graphene-plate lattice composite material, wherein the plurality of fullerene-derived carbon columns are derived from fullerenes fused to the first and second graphene sheets, wherein the plurality of fullerene-derived carbon columns are positioned on the graphene sheets with a spacing from about 0.5 nm to about 2 nm from each other, and wherein the composite material comprises a tensile strength in an x-axis parallel to the plane of the graphene sheets of at least 22.5 GPa.
