Aluminum reinforced with silicon carbide composites areextensively used in automobile industries ... more Aluminum reinforced with silicon carbide composites areextensively used in automobile industries and aerospaceowing to their favourable microstructure and improved mechanical behaviour with respect to pure aluminium but at a lower cost. Aluminium is remarkable for the low density and its ability to resist corrosion. The aim of present study istoevaluate the mechanical and microstructural properties of aluminum with silicon carbide (average particle size 30-45μm) reinforced in varying weight percentages (wt %) ranging from 0-15 wt% in a step of 5% each. Ultimate tensile strength, micro hardness and density of the fabricated composites were investigated as a function of varying SiC wt%. Microstructure analysis was carried out on casted composites using optical microscopy and scanning electron microscopy. From micrographs it is clear that fair distribution of reinforcing particles in the matrix and also observed some clustering and porosity in the cast material. Results revealed that, the addition of SiC reinforcement in the aluminum matrix increases the hardness and ultimate tensile strength gradually from 23 HV to 47 HV and 84 MPa to 130 MPa respectively.

The Granite-Epoxy (G-E) composites with Silicon carbide (SiC) and without Silicon carbide filler ... more The Granite-Epoxy (G-E) composites with Silicon carbide (SiC) and without Silicon carbide filler were prepared using the hand lay-up technique. Three-body abrasive wear tests with different loads/abrading distances were performed at room temperature by using a rubber wheel abrasion apparatus. The results showed that among the filled Epoxy composites tested, 20 wt. % granite and 10% SiC filled epoxy composites showed a better result. The systematic experimentation leads to identification of significant process parameters and material variables that predominantly influenced the specific wear rate. It is evident from Taguchi wear analysis that load plays a significant role followed by abrading distance, and material composition. Finally, the worn surfaces were examined using Scanning Electron Microscopy (SEM) to identify the various wear mechanisms.
