    摘要： 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/cm3 for a fiber, yarn, rope or cable and a density less that 1.5 g/cm3 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.

    摘要： High density compounds that can be used in extrusion-based 3D printing processes and methods for making the same are described. The high-density compounds can be made in the form of filaments by providing a thermoplastic material (such as ABS), providing a source of heavy metal (such as Bi2O3 powder), compounding the thermoplastic material and the heavy metal source to form high-density compound, and then extruding the high-density compound to form the filament shape. These filaments can be used to make a high-density product by melting the filaments in the printing head of a FDM 3D printer and then depositing the molten material in the 3D printer in successive layers to form the high-density product. The resulting high-density products exhibit an enhanced radiopacity because of the presence of the heavy metal, allowing the rapid manufacturing of radiation shielding components via the 3D printing process. Other embodiments are described.
