Abstract: Bicomponent carbon fibers may comprise an inner region that is at least partially surrounded by an outer sheath, each comprising at least one carbonized pitch. The inner region comprises 70 wt % or greater mesophase pitch that has been carbonized, and the outer sheath comprises up to 70 wt % mesophase pitch that has been carbonized. An amount of mesophase pitch in the outer sheath is lower than in the inner region. The bicomponent carbon fibers may be formed by extrusion of first and second pitch compositions having the requisite amounts of mesophase pitch, followed by carbonization.

Abstract: Polymer-nanocarbon composites, fiber-reinforced polymer composites, carbon matrix-nanocarbon composites, fiber-reinforced carbon matrix-nanocarbon composites, and methods for their manufacture are provided. The composites comprise one or more nanocarbon materials, optionally comprise fibers, and are produced from one or more polymers containing aromatic hydrocarbon moieties and/or aromatic heterocyclic moieties. The composite matrices may comprise thermoplastics or thermosets and may find use in, for example, infrastructure applications.
