AlburkiChemical Engineering Department, Faculty of Engineering, El-Mergib University, Al-Khums, Libya Abstract This work aims to study the change in the thermal conductivity of the polyester resin by adding alumina Al2O3 and different weights 10% 20% 30% resin and to study the effect of these additions on the thermal conductivity K. The resin material, and I tried to evaluate this change in behavior using Fourier's law of thermal conductivity to calculate the K value of the resin before and after adding alumina. The results showed that the thermal insulation increased by increasing the percentage of alumina in the resin and decreasing the thermal conductivity value. This graph summarizes the relationship between thermal conductivity and temperature.
