Manufacturing of Aluminium Composite Reinforced With Silicon Dioxide and Bagasse Ash and Characterization and Investigate the Mechanical Properties

Abstract

Silica sand and sugarcane bagasse-ash (BA) consuming as reinforcement in manufacturing of an Aluminum alloy (Al-2024) based matrix hybrid composites. The Aluminum matrix hybrid composites; fabricated by stir-casting method at 750 °C. Casting was performed in induction graphite crucible furnace and stainless steel stirrer having circular slots of diameter of 10mm and length of 500mm also the stirring blade at the end of the steel with 2mm thickness 40mm length and 20mm width. Addition of SiO2 and BA as reinforcement with nine compositions proportions, in the first case 5%, 10%, and 15% BA with Al2024. In second case 5%, 10%, and 15% Silica sand with Al2024. In third case 5%, 10%, 10% BA and 5%, 10%, 10% silica sand with Al2024. The fabricated composite was solution heat-treated (T3). The influence of the reinforcement has identified through different mechanical and microstructural tests. The mechanical properties measuring performed with Rockwell hardness and tensile strength, bending/flexure with universal testing machine. Samples have been prepared as per the ASTM E10, E8 and E290 standards respectively. The selected application of aircraft fuselage structure data used for the result as a sample. The application modeled and analyzed with SOLIDWORK 2017 and ANSYS 2020 R2. The Result shows that there is bigger outcome of reinforcing bagasse-ash with different composition in aluminum matrix reinforced and heat-treated composites. On the third case more improved mechanical properties have been achieved as compared to case one and two of BA & SiO2 combination. It shows that the selection of BA & SiO2 as reinforcement has one of the most significant criteria for the fabrication of aluminum matrix reinforced composites.
