Study of the Mechanical and Thermal Properties of Polyester Composites Prepared with Nylon66

In this research, polymeric composites were prepared from unsaturated polyester resin as a base material with Nylon 66 as a reinforcement material with different weight percentages (1%,2%,3%,4%,5%) and through the results it was found that the highest value was (Hardness strength, Compressive strength, Impact strength) when reinforced by weight (5%) at room temperature, but when treated at temperatures  (8.55) ℃, it was found that both the tensile strength and compressive strength increased at 55 ℃ and decreased at 8 ℃, while Impact resistance decreases at temperatures (8.55) ℃  It was also found that the thermal conductivity decreased at all temperatures (8.55)℃, which indicates that the polymeric composites consisting of unsaturated polyester resin reinforced with Nylon 66 are good heat insulators
