Abstract


Glass Fiber Reinforced Epoxy(GFRE)  composites are one of the most widely used composite materials due to its light weight and higher stiffness, used for aerospace, marine and other industrial applications The investigation aims to develop glass-epoxy composite with addition of SiC and fly ash as fillers with different weight fractions and to characterize the mechanical and damping properties.  In this work the SiC and fly ash powder is mixed as fillers with epoxy resin. The SiC and Flyash reinforced glass fiber epoxy composites are fabricated using hand lay-up process by varying the different weight percentages (0%, 2.5%, 5%,7.5%,and10%) of SiC and fly ash. The tensile strength of these specimens are observed experimentally by Universal Testing Machine(UTM).The free vibration behavior of SiC and fly ash reinforced glass fiber epoxy composites is studied on cantilever type boundary conditions using impact hammer technique. The objective of this work is to study the influence of SiC and flyash on glass fiber epoxy composites to know the behavior of tensile and damping properties. Experimental results shows that the tensile and damping properties are improved very much for 10%SiCand Flyash reinforced GFRE composites.
