الملخص EN

The objective of present research is to study the changing in thermal conductivity of unsaturated polyester resin by additive the silica material (SiO2) as a filler with different Weight percent (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, Where it change from(0.33 W/m.ºC) before added oxide to (0.23 W/m.ºC) after addition (30%) from silica at temperature (50 ºC) which the best value from oxide additive.
