  • Publication number: 20140213133
    Abstract: An antenna apparatus includes an electrically conductive section having peripheral edges, an antenna element coupled to the electrically conductive section, which transmits or receives electromagnetic signals, and an electromagnetic absorbing carbon material component. The carbon material component is generally disposed adjacent to the electrically conductive section, and includes a border region extending beyond the peripheral edges of the electrically conductive section. The carbon material component can be constructed of a carbon fiber fabric in which the carbon fibers are arranged to increase the effective signal to noise ratio of the antenna apparatus and enhance antenna performance without increasing the baseline power consumption level. The carbon fibers can be coated with silicone to insulate them externally while enhancing their lengthwise conductivity.

  • Patent number: 8501643
    Abstract: Basalt filament is manufactured such that the fiber diameter can be controlled and the filament is not severed during winding. A network former and a glass modifier are formed and maintained with respect to basalt rock ore, and the crystallization and binding of basalt fiber are inhibited, the heat-resistance property of basalt fiber is greatly improved from the conventional 750° C. to 850 or 900° C., and significant cost reduction is achieved over conventional products. The method includes: grinding basalt rock as a material; washing a resultant ground rock; melting the ground rock that has been washed; transforming a molten product into fiber; and drawing the fiber in an aligned manner, and winding it. The temperature of the molten product in the melting step is 1400 to 1650° C., and log ? is 2.15 to 2.35 dPa·s and preferably 2.2 to 2.3 dPa·s, where ? is the viscosity of the molten product.

  • Publication number: 20040242107
    Abstract: A non-woven flame blocking fabric and method utilizes a fibrous blend of a concentration of cellulosic organic fibers (A) and a concentration of inorganic fibers (B) to which a flame retardant composition (C) is applied. The concentrations of fibers are blended and treated to form a flame retardant fiber blend capable of forming a non-woven flame blocking fabric that upon exposure to flame forms a reinforced char barrier (D) that prevents the flame from igniting any flammable substrate. The reinforced char barrier (D) includes the carbonized cellulosic organic fibers and melted inorganic fibers. A concentration of binder fibers or powders (E) may alternatively supplement the fiber blend to produce a low profile flame blocker fabric upon activation and calendaring. The fabric preferably has a low profile as a result of compaction and bonding, but the fabric may be provided as a high-loft web.
