What is it about?
In this contemporary work, particulates of coconut shell ash and boron carbide were reinforced with an atomized aluminium powder hybrid composites was prepared by the powder metallurgy process. The process parameters in powder metallurgy influence the various material properties. Compaction pressure, sintering temperature and weight percentage of coconut shell ash were selected as influencing parameters. An empirical relationship has been formulated using response surface methodology. The properties such as hardness, relative density and percentage of porosity are considered a response. Variance of analysis was employed to determine the significance of process parameters on the responses and to determine the optimal combination of parameters.

Why is it important?
Aluminium hybrid composites are a new generation of MMC that have the potential of satisfying the recent demands of advanced engineering applications.
Perspectives
Agricultural wastes facilitate application towards innovative and new spheres of economic concern and exploit their full potential as valuable resources. Very scarce researches have been focussed on using agricultural waste as hybrid reinforcement combined with ceramic material.
