摘要： The invention is directed to carbon fibers having high tensile strength and modulus of elasticity. The invention also provides a method and apparatus for making the carbon fibers. The method comprises advancing a precursor fiber through an oxidation oven wherein the fiber is subjected to controlled stretching in an oxidizing atmosphere in which tension loads are distributed amongst a plurality of passes through the oxidation oven, which permits higher cumulative stretches to be achieved. The method also includes subjecting the fiber to controlled stretching in two or more of the passes that is sufficient to cause the fiber to undergo one or more transitions in each of the two or more passes. The invention is also directed to an oxidation oven having a plurality of cooperating drive rolls in series that can be driven independently of each other so that the amount of stretch applied to the oven in each of the plurality of passes can be independently controlled.

摘要： A melt-spun highly oriented and crystalline thermoplastic filament or fiber having a tenacity of at least about 10 g/d, an elongation less than about 15%, and a modulus of at least about 130 g/d. A method of making highly oriented and crystalline thermoplastic filaments has been developed that comprises extruding a thermoplastic polymer to form at least one molten filament. The at least one molten filament is introduced into a horizontal liquid isothermal bath. The bath is maintained at a temperature between the glass transition temperature and the melting temperature of the thermoplastic polymer. The bath increases the tension along the molten filament to form at least one partially oriented and low crystalline filament. The partially oriented filament is drawn to form the highly oriented and crystalline filament.

摘要： Disclosed is a method for preparing hollow carbon fibers having an empty space in the cross section thereof. More specifically, the disclosed method includes preparing a spinning solution of an acrylonitrile-based polymer having a viscosity ranging from 2000 to 5000 poise at room temperature; spinning the prepared spinning solution using a spinneret designed for spinning hollow fibers; super-drawing and 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 a lower specific gravity by 10 to 50% than conventional hollow carbon fibers (solid), but have similar mechanical properties to the conventional fibers. Furthermore, in the method, the diameter of carbon fibers can be adjusted. Thus, it is possible to widen the application of hollow carbon fibers.
