ELECTROMAGNETIC SHIELDING EFFECTIVENESS OF CARBON EPOXY PARTICULATE COMPOSITE PLATES
Keywords:
EM Shielding, Carbon Particulate Composites, DOE, MinitabAbstract
An investigation was conducted on Electro Magnetic (EM) shielding effectiveness of carbon epoxy particulate composites. The specimens were tested in the X band (8 GHz to 10 GHz) and S band (2 to 4 GHz) in EM spectrum. A better shielding effectiveness material was obtained through experiments and the EM shielding effectiveness of carbon particulates of various micro structures were compared. Design of experiments with Minitab 14 was used for optimizing of the results in experiments. The various input parameters selected were the thickness of the material, distance from source, weight fraction and frequency. The output parameters selected were attenuation and shielding effectiveness. Study was carried out experimentally, graphs plotted and results were analyzed.
