| Abstract | ||
| This paper discussed the effect of frequency on dielectric properties of different weight fraction of Cu powder reinforced epoxy composite materials. Dielectric properties of epoxy material was reinforced with (0, 5, 15, 30, 45) % weight fraction of Cu powder at frequencies ranges ((50Hz -106Hz) at room temperature. The results of this study show these dielectric constants and dielectric losses factor were increased with increasing in weight fraction due to interfacial polarization. The results also, exhibit that dielectric constant (έ) and dielectric loss factor (ε”) decreased with increasing of frequency account of electric polarization changed with an electric field changed. | ||
