Thermal conductivity of raw Al 2 O 3 /epoxy composites was 0.50 W/(m*K). This value increased by approximay 238% at the 30 wt% filler fraction. The incorporated Al 2 O 3 contributed toward bridging the heat-transfer route in the matrix, increasing the thermal conductivity of samples, as depicted in Fig. 6(a). This improvement was also caused
alumina has much higher thermal at lo w temperatures, the precision of steady-state laser technique, used in the current study, is not as good due to small thermal gradient across the test specimen at low temperatures. Thicker test specimens of alumina may improve the precision. Thermal
