Abstract

The purpose of this study is to investigate the manufacturing processes and mechanical properties of composites made of marine shell powder, coconut shell powder, and aluminium. In our project, the MMC was made of aluminium with seashell powder and aluminium with coconut shell powder. A stir casting process fabricated the Composite. The composition of aluminium, seashell powder and coconut shell powder varies. According to the criteria established by the American Society for Testing and Materials (ASTM), a morphological and mechanical behaviour examination of the material was carried out. The microstructure exhibits a relatively uniform dispersion of reinforcement particles inside the matrix alloy, with a reduced number of visible remaining pores. The maximum tensile strength of composite material is 176.34 kN in Al- reinforced 10% seashell powder; the composite materials have a higher yield strength of 146.38 kN in Al + 5% coconut shell powder. The matrix dislocation density and elastic modulus fluctuations are both increased, resulting in 205.46 kN at Al + 5% coconut shell powder shows an increase in the flexural strength of the material. As a consequence of the improved grain refinement and decreased porosity, the impact strength of the material increased by 61.60 kN at Al + 10 % Seashell powder. Max Hardness is achieved at Al + 5% coconut shell powder is 65.75 HBW. Corrosion test proves that material is withstanding upto 16 hours in salt water without white rust fornmation.

Keywords: Aluminium, Metal matrix composite, Mechanical testing, seashell powder, and coconut shell powder.
