Abstract<\/span><\/h3>\n

\u00a0This Work investigated the preparation of polymeric blends of epoxy resin and unsaturated polyester resin (Ep+UPE), (Optimum mixing ratio) selection was based on the results of the impact test. Differential Scanning Calorimetry\u00a0\u00a0 (DSc) test showed that the prepared polymer mixes were homogeneous and the best results was for (Ep80%+UPE20%) blend which exhibited one value for glass transition temperature (Tg) equal (112\u00b0C).<\/span><\/h3>\n

After \u00a0determining the best mixing ratio, (Ep80%+UPE20%). There sets of the polymer mix samples were prepared the first was the (Ep+UPE) blend, and then prepared alone composite material consist of the polymer blend (Ep+UPE) with the different weight percentage of magnesium oxide (4,8,12)%wt . Also, a hybrid composite material prepared consist of the polymer blend (Ep+UPE) plus the magnesium oxide and Zinc oxide powder (Ep+UPE+MgO+ZnO) have the same weight percentage as mentioned above . The preparation process for the composites material was done using the Hand-Layup molding method. Also included in this study were some mechanical and physical tests like Impact resistance, tensile strength, young modulus, compressibility, hardness, thermal conductivity. In addition diffusion coefficient test was also conducted using chemical solutions that include nitric acid (HNO3), sodium hydroxide solution (NaOH) at concentration of (0.05N) as well as distilled water of the results obtained for the mechanical tests, samples with (8%) MgO powder for the alone composite material (Ep+UPE+MgO) had the best value for the Impact strength, tensile strength and the young coefficient which takes of the values of (7.41MPa),(8.30MPa),(13.79MPa) respectively.<\/span><\/h3>\n

The best value for the alone composite material was (7.04MPa) for the compressibility test. The hybrid composite material has the 4% wt of (MgO+ZnO) powder possesses the best value of impact strength ,Tensile strength and young modulus (27.33MPa),(8.09MPa),(15.2MPa) respectively while the percentage weight of 8% wt of (MgO+ZnO)\u00a0 posses best value of compressive strength was (4.70MPa).<\/span><\/h3>\n

The hardness test results showed an increase in the hardness value after reinforcement with the alone composite material, and the hardness value increases by increasing the weight ratios of the magnesium oxide added for the hybrid composite material a noticed reinforcement and decrease in the value of hardness after continue to decrease with the increase in the ratio of magnesium oxide and Zinc oxide additives. For the physical tests, thermal conductivity values were decreased in values after the alone composite material reinforcement. It continues to decrease with the increase of the added ratios of the alone composite material. The hybrids were also showed noticed decrease in the values of the thermal conductivity after reinforcement, but increases as the added percentage increases. For the diffusion test, the polymer mixture (Ep+UPE) had the lowest value in distilled water, where the diffusion coefficient was (1.905×10\u00af\u00b9\u00b2 m\u00b2\/sec).In the acid solution; the ratio of (12%) for the alone composite material had the lowest value for the diffusion coefficient (2.498×10\u00af\u00b9\u00b2m\u00b2\/sec). For the basic solution, the ratio of (12%) was also showed lowest values diffusion coefficient (1.82×10\u00af\u00b9\u00b2m\u00b2\/sec) . The hybrid composite material lowest diffusion coefficient value in the distilled water at the ratio of (12%) (5.79×10\u00af\u00b9\u00b2m\u00b2\/sec), while for the acidic solution the samples with (8%) additives’ processed the lowest value of (4.157×10\u00af\u00b9\u00b2m\u00b2\/sec). The basic solution samples at (12%) reinforcement displayed the lowest value for the diffusion coefficient with a value of (12.968×10\u00af\u00b9\u00b2m\u00b2\/sec).<\/span><\/h3>\n","protected":false},"excerpt":{"rendered":"
