Abstract

We study electrical conductivity behavior of Cu-powder reinforced epoxycomposite material in different solutions (distilled water, tap water &3.5%NaCl)with a weight fraction (5, 15, 30 &45) was investigated for (7) weeks immersiontime. The results exhibit that electrical conductivity increases as increasingimmersion time due to the specimen was absorbed the solutions. The maximumvalues were reached with 3.5% NaCl solution because of Cl ions whereas electricalconductivity not apparent in distilled water was attributed to pure water containingno ions is an excellent insulator.
