  • Patent number: 8501146
    Abstract: Disclosed is a method for preparing hollow carbon fibers having an empty space in the cross section thereof. More specifically, the disclosed method includes melt-spinning an acrylonitrile-based polymer by using a supercritical fluid as a plasticizer; drawing spun fibers to prepare hollow precursor fibers; and stabilizing and carbonizing the hollow precursor fibers to prepare the hollow carbon fibers. The hollow carbon fibers obtained by the disclosed method have at least a 10 to 50% lower specific gravity than conventional hollow carbon fibers (solid), but have similar mechanical properties to the conventional fibers. Furthermore, the diameter of carbon fibers can be adjusted, thereby making it possible to widen the application of hollow carbon fibers.

  • Publication number: 20130065052
    Abstract: A new class of high modulus polypropylene multifilament fiber and/or yarn is provided. Such a multifilament fiber and/or yarn exhibits an exceptional combination of high strength and toughness with low weight and density. The inventive fibers thus permit replacement of expensive polymeric fibers within certain applications with lower cost alternatives, or replacement of high density components with such low density fibers, without sacrificing strength or durability. Such multifilament fibers are produced through melt-spinning processes and exhibit highly unique microstructures therein, including significant void volumes, interspersed and crossed voids, and nanofilament bridges within such voids. Such microstructural characteristics appear to impart the exceptional properties noted above.
