Abstract:

Improvement of mechanical properties of polymer-based composite materials with high fill ratio and mechanical properties is the main reason for the improvement of mechanical properties by addition of carbon-based compounds to the matrix. In this study, 1, 3, 5 and 7% nano plaques were added to the filling composition in order to improve the mechanical effects of the 14-micron aluminum oxide (Al2O3) particles added to the polypropylene matrix by 40% by weight. Hybrid composites were obtained by mixing in high-speed thermo-kinetic mixer, tensile and 3 point bending tests were performed with universal mechanical test machine and their mechanical properties were investigated. The samples taken from the rupture points of the tensile specimens were examined under a scanning electron microscope (SEM) and the distribution of alumina and graphene particles was observed. According to data, it was seen that tensile strength of composites was increased nearly 12% and flexural strength increased almost 20% with the graphene particles addition into the PP matrix. The distribution of graphene particles in PP was homogenous and regular.
