【 摘 要 】

The adhesion at the interface between the matrix and reinforcement plays a major role in determining mechanical properties of Aluminum Metal Matrix Composite (AMMCs). Various techniques are developed for better properties of AMMCs. Some are complex in nature and expensive. Simple and cheap methods are still to be found to satisfy the stringent demand of customers. In the present experimental study, extensive and inclusive laboratory experiment is done which possibly improves the wettability between the matrix and reinforcement. The first phase of the experiment is preparation of matrix material, reinforcement and fluxes. This includes composition analysis of aluminum, crushing particles of SiC and analyzing their size distribution. The second phase is the selection of the manufacturing process, which possibly enhances the wettability between the matrix and reinforcement. As a result, test samples of a composite having different content and compositions of reinforcement are prepared using squeeze casting.
