Through this research, polymeric composites were prepared from Addition of epoxy resin with iron filings in certain weight ratios (0.5%,1%,1.5%,2%,2.5%,3%,4%,4.5%,5%) as a reinforcement material. The comparison was made between polymeric composites  Before and after the cementing process , After a series of experiments, it was found that the best weight percentage was (1%),This addition was done at different temperatures (8,25,55) °C, The results when compared before and after the reinforcement process for the composites showed that the thermal conductivity the thermal conductivity increased after the strengthening process, for the mechanical properties, Impact test, Hardness and compressive strength, they increased at 25°C and increased at processing temperatures(8.55)°C.
