Graphene has been used in nanocomposites as constituents/doping in plastics or epoxy providing dramatic enhancement of the mechanical properties but have not progressed past the laboratory level novelty. This invention can provide a graphene based composite structure with a density less that 1.9 g/cm.sup.3 for a fiber, yarn, rope or cable and a density less that 1.5 g/cm.sup.3 for a sheet both structure have tensile and shear strength greater than either Aluminum or Steel; thus providing a graphene material that is both much lighter and stronger.

A method for coating a textile material, said method includes the following steps: a) incorporating activated carbon in powder form into a coating composition including an aqueous solvent and at least one organosilicon precursor, wherein the organosilicon precursor represents from 5 to 50% by volume relative to the whole of the aqueous solvent and organosilicon precursor, b) impregnating the textile material with the coating composition by padding and c) drying the impregnated textile material, characterised in that the coating composition contains no polycarboxylic acid or catalyst.

In a method for producing a PBO fiber with increased resistance against UV-caused degradation, a coating is provided on the PBO fibers, wherein the coating comprises graphene oxide cross-linked by polymerization with glutaraldehyde and resorcinol. The fibers are useful for lighter than air vehicles.
