▎ 摘　　要

NOVELTY - Formation of nanocomposite fiber involves suspending carbon powder containing graphene flakes in a carrier fluid, adding a solid polymer material to the carrier fluid to form a mixture, heating, and at least partially dissolving the solid polymer material within the carrier fluid, removing the carrier fluid from the mixture and forming a polymer into a fiber carrying the graphene flakes. USE - Formation of nanocomposite fibers (claimed). Uses include but are not limited to formation of textiles (e.g., fabrics), yarns, braided ropes, and cords used to produce ballistic materials. ADVANTAGE - The nanocomposite fiber has improved mechanical performance e.g. tensile strength, impact absorption, cut and abrasion protection, fatigue resistance and fracture strain. The ballistic material produced using the nanocomposite fiber has improved performance, reliability, durability, impact absorption and improved strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nanocomposite fiber, which comprises ultra-high molecular weight polyethylene polymer matrix containing amorphous and crystalline regions. The graphene flakes are dispersed in and carried by the ultra-high molecular weight polyethylene polymer matrix without any covalent atomic bonds between the graphene flakes and the ultra-high molecular weight polyethylene polymer matrix. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an extrusion process used to form a nanocomposite fiber.
