Abstract
This research is a study of the effect of Al2O3 powder on physical and mechanical properties of the polymer hybrid composites based on unsaturated polyester resin reinforced with carbon and glass fibers. The samples were made by a hand lay-up method according to ASTM standard for various volume fractions of additives. The polymer composites materials reinforced with carbon and glass fibers are the most used in manufacture of components such as pip, part of aerospace, and leisure industries and automotive.The polyester resin matrixwas strengthened with 3% carbon and glass fibers with 1%, 3%, 5%, 7% Al2O3 powders. The water absorption, hardness (shore D), impact test, and flexural strength properties are studied. The results show the specimens (UP+3%C.F+7%Al2O3) and(UP+3%G.F+7%Al2O3) had the maximum hardness (shore D) and water absorptionwhen compared withunfilledpolyester resinspecimen, it can be observed that the specimens(UP+3%C.F+5%Al2O3) and (UP+3%G.F+5%Al2O3) have maximum impact strength and flexural strengthcompared with specimens (UP+3%C.F+7%Al2O3)and (UP+3%G.F+7%Al2O3) .
