| Abstract | ||
| We study electrical conductivity behavior of Cu-powder reinforced epoxy composite material in different solutions (distilled water, tap water &3.5%NaCl) with a weight fraction (5, 15, 30 &45) was investigated for (7) weeks immersion time. The results exhibit that electrical conductivity increases as increasing immersion time due to the specimen was absorbed the solutions. The maximum values were reached with 3.5% NaCl solution because of Cl ions whereas electrical conductivity not apparent in distilled water was attributed to pure water containing no ions is an excellent insulator. | ||
