MECHANICAL PROPERTIES OF SIC AL2O3FILLED GLASS EPOXY COMPOSITES

In the present study, glass-epoxy based composites were fabricated by filling with nano size SiC and Al2O3 filler particles. The hand lay-up approach was used for fabrication of random oriented short E-glass fibre reinforced epoxy composites filled with SiC and Al2O3 powder particles. The volume percentage of filler materials in the composites were varied, SiC was varied from 0, 5 and 10%, whereas Al2O3 was kept constant at 5%. Mechanical characterization were studied effectively. The filled and unfilled SiC and Al2O3particles, were tested for micro-hardness, tensile strength, and flexural strength in according with ASTM standards. It was observed from the studies that using particles as fillers improved the mechanical properties of the E-glass fibre substantially
