ABSTRACT The Development in the applications of Aluminium Alloy in the industries is not unconnected to its lighter weight, recyclability, cost, and availability. The cost of reinforcement materials cause the increase cost of composites production thereby limiting its applications. Efforts to reduce the cost of composite materials is to source alternative reinforcement materials. The addition of pulverised periwinkle shells(PPS) would strengthened Aluminium Alloy, and increased its horizon of applications. To determine the percent weight of Pulverised Periwinkle Shells(PPS) that would give excellent strength to Aluminium alloy(AA) in increasing its hardness and tensile strength. The Periwinkle Shells were boiled in water at 1000C for thirty (30) minutes, washed using distilled water, dried in an oven at 1050C for 24hours.The periwinkle shells were pulverised and discretised using a sieve shaker of mesh sizes of 70 and 53 microns. The grade of 53microns was used because it was finer. The compositional analysis of AA, PPS, and charge calculations were done and the following percent weight of PPS were used: 10%; 15%; 20%; and 25% as reinforcement, and 0% of as-cast AA was used as the control. Gas crucible furnace was used to melt the AA at 7500C, and the liquid AA was taken out from the furnace and 1% of magnesium was added before the addition of the percent weight of PPS, and the mixture stirred using mechanical stirrer. The slurry was taken back to the furnace and heated, and at 7500C it was fetched and poured into the reusable moulds to produce the test coupons for Hardness and Tensile strength test and the process was repeated for all the compositions. Hardness and tensile strength test was done using Indentec universal hardness tester and Universal testing machine. The results obtained from the study shows that 20% PPS-AA Composites exhibit the highest hardness number HRB (85.35) and tensile strength value; 204.25MPa compared with unreinforced AA and other reinforced AA. From the results obtained 20% PPS-AA composite would be suitable for applications that required good hardness and tensile strength.
