Fabrication and Experimental Investigation on Mechanical Properties of Quartz Particulate Reinforced Aluminium Composite
Abstract: Composites are processed by adding a reinforcement phase in a base metal. The base material is known as a matrix and the constituent that is added is called reinforcement. The matrix acts as a support while the reinforcements attach themselves in their respective positions which results in the synthesis of a material which has different mechanical and thermal properties compared to their raw materials. Since aluminium is used as a …
