| Abstract | ||||
| Binary and ternary polymeric blends from epoxy (EP), unsaturated polyester (UPE), with silicone rubber (room temperature Vulcanizes (RTV)) were prepared. Silicone rubber (SR) was mixed well with sufficient amount of ethanol before its adding to resins. These blends were reinforced by nano Al with 1% wt, and Al2O3 with 1% wt to develop the properties of blends. TGA and DSC were obtained from the thermal degradation computed by using Coast-Redfern technique. Kinetic and thermodynamic parameters were studied for all specimens were presented a good linear correlation coefficient close to unity using Minitab 16. DSC profiles for all composites shows there are a single endothermic peak which represents the glass transition temperature. Activation energy of binary and ternary epoxy blends decreases with increasing the percentage of SR while the addition of Al and Al2O3 nanoparticles shows an increase in the activation energy when added to binary and ternary blends for epoxy. | ||||
