Abstract

The experimental investigation of the effect of adding alumina oxides Al₂O₃ nanoparticles on mechanical properties of unsaturated polyester resin has been studied. The Mechanical properties were evaluated by tensile, hardness and impact test. The study involved adding alumina oxide nanoparticles with size 45nm in different weight ratio which are 0,3,5,7, and 9%. The specimens were manufactured using hand-layup technique. The results showed that the increasing of AL₂O₃ into the polyester matrix can improve the tensile strength, elastic modulus, hardness, and impact strength of polyester to 18.91, 10.44, 1.21, and 221.53%, respectively, when the AL₂O₃ weight fraction reached 5%. However, the mechanical properties decreased when the Al₂O₃ nanoparticles weight fraction reached 7% and 9% . The Optical microscopes observations revealed that the nanoparticles were more homogeneously dispersed at 5%.
