Abstract: The fabrication of Engineering materials with properties combination of high hardness, impact resistance, ductility and light weights can only be obtained from metallic super alloy materials, which has led to the development of metal matrix composites, (MMC). Aluminium/Silicon carbide and Aluminium/Boro-silicate glass materials, were separately fabricated owing to their low density, high temperature strengths, etc.
Stir-casting process of fabrication was adopted because of it’s simplicity and flexibility, and also the use of sand mould.
The metal matrix composites (MMC’s) bars and circular plates are prepared with varying the reinforced particles by weight fraction ranging from, 5%, 10%, 15%, 20% and 25%. The average reinforced particle size of silicon carbide and also borosilicate glass was 100μm.
The mechanical tests of hardness, impact, ductility and tensile tests were carried out. Also the specific weights were also evaluated.
From the various mechanical tests and the physical property evaluation results it shows that aluminium reinforced with borosilicate glass material increases in strength and decreased specific weight with increasing reinforcement, and that 25% borosilicate glass reinforcement provides the best mechanical hardness and tensile strengths and also the best physical properties.
Metallographic analysis of the specimens, using Optical microscopic process, shows even particle distribution of reinforcements.
