Mechanical properties and characterization of zirconium oxide (ZrO2) and coconut shell ash(CSA) reinforced aluminium (Al 6082) matrix hybrid composite

This study focuses on the microstructure and mechanical properties while incorporating zirconium oxide and coconut shell ash particles in Al 6082 matrix composites. Zirconium oxide and coconut shell ash particles were varied from 0 to 10% and fabricated by stir casting process. The fabricated composites were subjected to X-ray diffractometer and SEM to confirm the presence of zirconium oxide and coconut shell ash particles. Hardness, density, impact strength, tensile strength, ductility and flexural strength analysis were carried on the developed hybrid composites to study the mechanical properties of composites. Scanning electron microscopy study were carried on the fractured tensile and impact test specimen to analyse the fracture mechanism. (C) 2018 Elsevier B.V. All rights reserved.
