Study the effect of volume fraction on thermal conductivity values for polyester particles composites


The objective of present research is to study the changing in thermal conductivity thermal of unsaturated polyester resin by additive the silica material (SiO2) as a filler with different Weight amount (10%,20%,30%) to resin and study the effect of this additive on thermal conductivity coefficient (k) of the resin . Fourier equation was used to calculate the changing in thermal conductivity coefficient (k) for unsaturated polyester resin before addition silica material and after ,where the results show increased thermal insulation of the resin by reduced thermal conductivity coefficient value after addition this material . Also the value of thermal insulation increased with increasing of additive percentage of silica as illustrated in diagrams which represent the relation between thermal conductivity coefficient with temperature.
