Effect of Zirconia-Alumina Additives on Some Mechanical and Physical Properties of Epoxy Resin for Industrial Applications

The performance of the composite is improved by the addition of ceramic particles to the polymer resin, making such materials useful in the automotive and aerospace sectors. In order to evaluate the properties of epoxy resins, zirconia and alumina are combined in this study at weight percentages of 5%, 10%, 20%, Aand 30%. AThe main goal is to use the "hand lay-up" method to assess how various ceramic additions affect the mechanical and physical characteristics of the epoxy matrix, including its tensile test, impact test, hardness test, density and water absorption test. Alumina adds hardness and wear resistance, whereas zirconia is well-known for its high fracture toughness and energy absorption capacity. It is believed that mixing these fillers would increase composite performance synergistically. The most appropriate ratios to optimize the reinforcing effects are investigated in this study. The best mean values of the tensile strength and impact strength (8.35MPa, 22.37KJ/m2) were at the samples (Epoxy-10% zirconiaalumina). By raising the concentration of the weight fractions of zirconia-alumina in epoxy up to 10%, Athe percentage of water absorption values increased; the samples with 10% zirconia-alumina in epoxy had the optimum water absorption percentage (0.253%). The results emphasize the importance that interfacial bonding and appropriate filler distribution are to obtaining excellent mechanical characteristics.
