ABSTRACT

This study is about the production and characterization of aluminium alloy-Particulate periwinkle shell composite. Composites were produced at 1 %, 5%, 10% and 15% weight fraction of Particulaf'e periwinkle shell (PPS) fillers and the aluminium alloy was cast neat at 0%PPS which served as the control. The microstructures of the composites were studied with Optical Microscopy. Mechanical properties of the composites such as tensile properties (tensile strength, Young's modulus, energy at break and percentage elongation at fracture) and hardness were experimentally determined in the Engineering Materials Development Institute (EMDI) using lnstron Universal Testing machine, optical microscopy and microhardness tester. The Optical microscopy analysis showed that interfacial interactions existed between the PPS and the aluminium alloy matrix. Results of the mechanical property tests showed increase in tensile strength, Young's modulus and hardness at low particle sizes while at high pmticle sizes, the results of the mechanical property test showed decrease in the mechanical properties due to poor wettability of the filler by the matrix, low surface area and high porosity at high pmticle sizes. The increase in mechanical properties at small particle sizes is as a result of good wettability of the filler by the matrix, high surface area of the filler and less porosity. It was deduced from the study that aluminium alloy-Particulate periwinkle shell composite is suitable for engineering applications such as aeronautical and automobile applications due to their low weight to strength ratio. Also, it could be used in engineering structures, marine application, automotive bumpers and sporting goods due to the high strength and hardness. Coating of the surface of PPS with big pa1ticle sizes with coupling agents could be done to improve interfacial adhesion and the particle size of PPS could
