Abstract
ABSTRACT Aluminium and aluminium alloy MMCs (AAMMCs) tend to be the most explored materials in MMC development due to their broad range of properties such as wear resistance, light weight, strength with durability, and improved damping capabilities for automobiles, aerospace, and marine at reasonable production costs among other materials. However, the reinforcements chosen will have an impact on the properties of the composite, bridging the gap between the research problem and the desired specialised application. In that effort, numerous researchers have subsequently explored the influence of AAMMCs with various reinforcements aimed at increasing damping properties. In this work, MMCs alloy as matrix and copper particles as reinforcement sat 0 to 15% were synthesised using stir casting route. MMCs/Cu MMC samples were then investigated using SEM to ensure the dispersion of Cu particles in MMCS MMC before being exposed to a frequency response function to determine the modal frequencies and damping ratios. The acquired results on the influence of Cu particles in MMCs matrix on frequency responses and damping ratios were clearly presented.
