| Abstract | ||
| The main goal of this research is to improve some of the mechanical properties of unsaturated polyester by using available and cheap particulate fillers, such as reinforcement with iron filing powder with a grain size of 75 microns. In this research, unsaturated polyester composites were prepared with iron waste (iron filings), and some mechanical and thermal properties were studied at certain weight percentages (5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50%). As supporting materials. A comparison was made between the polymeric composites before and after the reinforcement process, and it was found that at a percentage (30%) they had good mechanical properties, and these additions were made at different temperatures (8, 25, 50) °C. The results before and after the reinforcement process for polymeric composites showed that there was an increase in the values of mechanical properties (compressive strength, hardness, and impact resistance) with a decrease in the modulus of elasticity (Young's modulus). The treatment was carried out at temperatures of 8.50 ºC, and there was a varying increase and decrease in the values of mechanical properties. It was also found that thermal conductivity decreased when the temperature decreased and increased when the temperature increased. | ||
