  • Electromagnetic Wave Absorber Using A Dielectric Loss Sheet, Method For Forming The Electromagnetic Wave Absorber, And Rotary Blade For A Wind Turbine Having An Electromagnetic Wave Function Using Same
    Publication number: 20130224023
    Abstract: Disclosed are an electromagnetic wave absorber using a dielectric loss sheet, a method for fabricating the same, and a wind turbine blade having an electromagnetic wave function. The electromagnetic wave absorber comprises: a support layer for providing a resonant space of electromagnetic waves; a highly conductive backing layer assigned to a back surface of the dielectric support layer; and a dielectric lossy composite sheet layer formed on a front surface of the dielectric support layer, said dielectric lossy composite sheet layer having such a dielectric permittivity so as to generate a resonant peak with the electromagnetic waves reflected from the highly conductive backing layer.

  • Multi-functional hybrid fiber by simultaneous multi-component deposition, composite material with the same, and method for manufacturing the same
    Patent number: 8057898
    Abstract: Provided are a multi-functional hybrid fiber, a composite material with the same, and a method of manufacturing the same. The multi-functional hybrid fiber includes a carbon fiber having a bundle of a plurality of continuous fibers, the continuous fiber having an external diameter of 5 ?m to 10 ?m, a nano particle attached to an outer surface of the carbon fiber by an electrophoretic deposition method, and a metal attached to the outer surface of the carbon fiber by an electroplating method. The nano particle and metal are mixed and attached to the outer surface of the carbon fiber by the simultaneous electrophoretic deposition and electroplating methods.
