Influence of Natural Filler Powder on the Some Physical Properties of Polyurethane Foam Composites
Journal Title: Engineering and Technology Journal - Year 2024, Vol 9, Issue 08
Abstract
An investigation was conducted to analyze the impact of incorporating perlite stone powder particles at different weight ratios (5, 10, 15, 25, and 35) on the polyurethane polymer's mechanical properties and thermal conductivity coefficient. The thermal conductivity coefficient of the samples was calculated using Holmarc's Lee's Disc apparatus device. The mechanical properties like compressive, tensile, and bending strengths were measured using a universal machine. The results indicated that increasing the perlite stone powder ratio leads to an improvement in the thermal insulation ability due to a decrease in the value of thermal conductivity, the addition of perlite stone powder enhances the ability of thermal conductivity at the ratio 5 wt. %, with a value equal to 0.106 W/m ºC, by increasing the thermal conductivities of the sample, while the result indicated a decrease in the thermal conductivity at the ratio 25 wt. %, with a value equal to 0.075 W/m ºC. Also, adding these percentages led to a rise in the values of the mechanical qualities represented by the flexural resistance, especially at the ratio of 10 wt. %, with a value equal to 33.9 MPa, and tensile strength increases at a ratio of 35 wt—%, with values equal to 2.57 MPa.
