In this research the additive effect of Zirconium Oxide (ZrO2), Copper oxide (CuO)nanoparticles to epoxy resin as a matrix have been studied, in addition tomanufacturing hybrid composites from the same nanoparticles which are (CuO/ZrO2)to epoxy resin as a matrix too. The hand lay-up method is using to manufacturing thecomposites from the epoxy resin and the nanoparticles with different weight ratios((0, 0.3, 0.6, 0.9) wt%), the thermal and dielectric tests have been done of all preparedcomposites. The effect of the weight ratio of the reinforcement materials on thethermal properties of all-polymer composites has been studied also. The practicalresults have shown that the differential scanning calorimetric (DSC) test has shownthat the glass transition temperature of all-polymer composites increases at all weightratios of reinforcement materials compared with pure epoxy and the highest value ofglass transition temperature is to the composite (EP-ZrO2) which equal (89.97 °C),also the crystalline melting temperature of all-polymer composites has shown irregularbehavior compared with pure epoxy by increasing the weight ratio of reinforcementmaterials. The effect of the weight ratio of the reinforcement materials on thedielectric properties of all-polymer composites have been studied, the practical resultshave shown a decrease in dielectric constant with increase the frequency for all weightratios of reinforcement materials, and also increasing the dielectric constant withincreasing the weight ratio of the reinforcement materials at the same frequency.
