Structure Property Correlation and Evaluation of Tensile Properties of Cenosphere Aluminium Composites

The automobile and aerospace industries relenting passion to enhance the performance of commercial and military applications is constantly driving the development of improved high performance structural materials. Composite materials are one such class of materials that play a signifi cant role in current and future aerospace applications. Composite materials are particularly attractive to both automobile and aerospace applications because of their exceptional strength and stiffness to density ratios and superior mechanical properties. Cenospheres are hollow alumino-silicate microspheres from fl y ash of thermal power stations and are a valuable industrial product due to successful combination of their technical and commercial parameters and can be used as a creation of functional materials. This paper discusses the use of cenospheres as reinforcement in the casting of aluminum metal matrix composite. Based on the metal, reinforcing phases, respective ratios, fl y ash cenospheres – aluminum composite with better features in terms of density, strength and hardness have been developed.
