| Abstract | ||
| In this paper, polymeric compounds were prepared from unsaturated polyester as a base material with sisal fibres with different weight percentages (1%, 2%, 3%, 4%, 5%) as a reinforcing material. After comparing the unsaturated polyester before and after reinforcement of the prepared compounds, it was found that there is an increase in the values of mechanical properties (Hardness strength, Compressive strength, Tensile strength, Impact strength) when reinforced by weight (4%) at room temperature; however, when treated at temperatures (8.55) ℃, it was found that the hardness, compressive and tensile strength decrease when heat treatment is at (8.55) ° C, the impact strength increases at higher temperatures and decreases at lower temperatures. 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. | ||
