  • Publication number: 20160177473
    Abstract: Prepare a polyolefin fiber having a diameter of 10 microns or less by extruding a molten polyolefin through die holes having diameters in a range of 250 to 500 microns to produce molten polyolefin fibers; drawing the molten polyolefin fibers to achieve a molten draw ratio in a range of 150 to 500 at a temperature in a range of 200 to 250 degrees Celsius; and drawing the polyolefin fibers in a solid state to achieve a solid state draw ratio of 3.0 to 4.0 at a temperature in a range of 40 to 100 degrees Celsius to produce polyolefin fibers having a diameters of 10 microns or less; where the polyolefin is characterized by being a polyolefin copolymer of ethylene and one or more than one alpha-olefin and where the copolymer has a solid density of 0.870 or more and 0.96 or less as determined according to ASTM D792.

  • Publication number: 20110059331
    Abstract: A method for joining a first component to a second component with a brazing material, the first component including an aperture for receiving the second component. The method includes positioning the second component within the first component via the aperture to form a gap between an inner surface of the first component and an outer surface of the second component, introducing by capillary action brazing material into the gap between the first component and the second component, and forming a join between the first and second component upon cooling of the brazing material introduced by capillary action. According to this first aspect of the present invention, the capillary flow of brazing material in the gap is diverted via a capillary flow diverter located in the gap between the first and second component.
