Advanced designed materials like metal matrix composites (MMC) consists of at least two constituent parts, a matrix and reinforcement of different materials such as metals, fibers, glass, organic compounds, or ceramics. An MMC can exhibit various enhanced properties like lightweight, high-specific strength and better ductility when compared with a single material. They have an advantage of the increasing mechanical and physical characteristics of the composite by varying the reinforcement percentages by volume fractions or orientation of fibers or laminates. The most popular materials such as aluminum, titanium, magnesium, and silicon carbide are possible reinforcement materials with aluminum as matrix. This work is mainly focused on study on behaviour of Aluminum Metal Matrix Composite, reinforced with Silicon Carbide and Titanium diboride for various kinds of loads and optimization for tensile strength and ductility. In this work two composite models of size 60µm * 60µm * 60µm with a reinforcement volume proportion of 20% of SiC and TiB2 were compared with the use of FEM tool (ABAQUS CAE). The tool is basically used for assigning different material properties such as young’s modulus, Poisson’s ratio, yield stress & different loads and to extract the results in the form of various stresses and strains on the modeled aluminum metal matrix composite (AMMC). The test results showed that the AMMC with SiC as reinforcement has better young’s modulus and tensile strength than AMMC with TiB2.
