Abstract

This paper centres on the autoclave moulding technique, offering a comprehensive analysis of the specimen fabrication process. The advanced composite manufacturing process involves the use of high temperatures and pressures during the curing step. This results in composite specimens that have a higher density and are devoid of any voids. Polyester, E-glass fibre, and SiC powder are the material components that make up the composite in this study. It is possible to construct composite specimens with nine different compositions by utilising the L9 orthogonal array, which is comprised of nine runs, four factors, and three levels. This array is utilized throughout the production process of the composite laminates. A total of nine distinct compositions were created by adjusting the parameters, which included the amount of time, the percentage of resin, fibre, and powder, and the amount of powder. Mechanical properties such as the specimens’ hardness, compression, and impact strength were tested as per the ASTM standard. To locate a superior specimen and determine whether the specimen is suitable for use in automotive applications, Grey Relational Analysis was utilized. The accomplishment was achieved through the optimization of the specimens that were placed throughout the entire testing process and the result was achieved.
