摘要

An improved method and apparatus for the production of a strand of reinforced graphite-foil yarn which is the basis of the braided graphite-foil yarns. To produce the reinforced graphite-foil strands what is needed is apparatus for a tapered, cone shaped circular die (34) having a specific geometry suitable for curling the fiber and adhesive coated surface inward upon itself, so that the curled ribbon (54) will adhere to itself when compressed into the final protrusion die (38,39) forming a finished fiber reinforced composite strand (40) of expanded graphite flake having suitable tensile strength, flexibility, and toughness to permit braiding, weaving and other processing making it commercially useful wherever a dry, lubricious, strong, flexible material is desirable.
