CFD Analysis and Fabrication of Aluminium Cenosphere Composites
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 5
Abstract
Metal matrix composites are engineered materials with a combination of two or more dissimilar materials, to obtain enhanced properties. Aluminium alloys reinforced with ceramic particles exhibit superior mechanical properties when compared to unreinforced aluminium alloys and hence are candidate for engineering applications. In the present investigation aluminium alloy is used as the matrix and cenosphere as the reinforcing material. The hybrid metal matrix composite is produced using conventional foundry techniques by casting route. The cenosphere is to be added in 2%, 4% and 6% by volume and also with the influence of the particle size of cenosphere, to the molten metal with Magnesium, which is the main parameter for the wet ability of cenosphere and aluminium alloy. The hybrid composite is to be tested for hardness, density, mechanical properties and impact strength. The density decreases with increase in cenosphere content. The impact strength increases with increase in cenosphere content. The resistances to dry wear and slurry erosive wear increases with increase in cenosphere content and hence this material can be used as bearing material. This composite material being less dense than aluminium can therefore be used in place of conventional aluminium alloys in aircraft components
