Abstract: There has been an increasing interest in composites containing low density and low cost reinforcements. So far most of the research work have been carried out by incorporating hard ceramic particles such as Al2O3, SiC, Flyash and graphite particles to soft matrix like pure aluminium A356, and many more alloys and very few worked on combination of reinforcements (hybrid composites). In the current work, an attempt has been made by combining two types of ceramic particles like flyash and silicon carbide in equal proportions for preparation of hybrid composites, which significantly improves the mechanical properties and wear properties of the Aluminum based MMCs.
Experiments have been conducted under laboratory condition to assess the mechanical characteristics of the aluminium FA/and SiC composite under different size particle conditions. This has been possible by fabricating the samples through usual stir casting technique. To enhance the mechanical properties the surfaces of the samples were studied under optical microscope to get an idea about the effect of particulate reinforcement on the micro structure behavior of the composite. Dispersion of FA and SiC particles in aluminium matrix A356 improves the hardness of the matrix material and also the mechanical behavior of the composite.
