Mechanical Properties of Hybrid Nano Graphene Oxide and Si Oxide Fiber-Glass Composites Materials

Abstract

Many practical applications in the automotive industry, aerospace applications, construction and others have benefited from the development in composite materials and reinforced by glass fibers and nanoparticles, in this work is improving mechanical properties from adding Nano particles and study of the effect of adding a mixture of nanoparticles of Graphene nanoparticles and Sio2 nanoparticles on the mechanical properties of hybrid compounds, Where the models of the hybrid compound were studied for the purpose of tests and by manual paving method. The mixture was mixed with different weight ratios (1%, 2% and 3%) for the purpose and evaluation of mechanical properties. The ultimate stress for unreinforced specimen with fiber glass is (80.77.7MPa) and its values and the best value was 77.69 Mpa for reinforced specimen by 2 % of Graphene ,92.13 Mpa for specimen by Sio2 at 3% and was 97.78 MPa at 2.5% hybrid from (Graphene and Sio2) , Also this addition improvement from hardness strength and impact strength and endurance limits at fatigue test and this happen due to good distribution of nanomaterials in composite materials as shown in SEM figures.
