MEASURING THE THERMAL CHANGE FOR PARTICLES COMPOSITE OF UNSATURATED POLYESTER AFTER ADDING SIO2 WITH DIFFERENT VOLUME FRACTION

Abstract

Silica material was added as a filler to unsaturated polyester resin with different weight percentage (1%,2%,3%) and study the effect of these additions on thermal conductivity coefficient of the resin. Fourier equation was used to calculate the changing in thermal conductivity coefficient (k) for unsaturated polyester resin before and after addition silica particles . 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.
