Technological advancements and promotion of compact structures always raises challenging tasks to a design engineers. The innovative ideas and creative designs are demanding hybrid mechanical properties. However, the conventional material may not be able meet this demand. The current work aims to investigate the mechanical properties of Al-PPS MMC and compared the properties of composites with the base material of aluminum 6061 (AA6061) alloy. Periwinkle shells were milled to particle sizes of 75µm and used to produce PPS-Al MMC at 1 and 2wt % filler loadings using two-step stir casting technique. The mechanical properties and microstructures of the composite materials were compared with AA6061. It was observed that the filler distributes uniformly in the matrix, it may due to due to two-step casting technique. The mechanical properties like hardness and Compression modulus was improved when the filler was used to reinforce the alloy. Microstructure reveals the uniform distribution of reinforcement with Al-6061.
