Effect of Chemical Solutions on Some Mechanical Properties of (Fe + Cu/UPE)

This research includes the preparation of polymeric composites by (Hand lay-up method) unsaturated polyester resin as a matrix material and (iron, copper) particles strengthening materials with different weight ratios (5%, 10%, 15%, 20%). The hardness impact strength properties are studied before after immersion in (NaOH) solution (HCl) at normality (0.3N) for period one (30 days). results showed that values increased increase percentage iron copper immersion, increasing ratio compounds For all samples, but their value was lower than normal conditions. And also these (HCL) were solution.
