Abstract
Graphene fibers made from a graphene film formed into an elongated fiber-like shape and composite materials made from the graphene fibers. The elongated fiber-like shape may be the graphene film in a rolled spiral orientation or the graphene film in a twisted formation. The graphene film has imide groups formed on at least an outer surface of the graphene film. Methods of increasing strength of a composite material include combining a resin matrix with a plurality of the graphene fibers to form a prepreg material and curing the prepreg material to form the composite material.
