To date, composite material has drawn significant attention due to its extended properties in various application. Many factors need to be considered in designing the composites which might leads to complex decision making. Therefore, this study focuses on analyzing and optimizing various factors including combination of material, volume fraction of fiber, ply angle, ply quantity, ply thickness and load applied via integration of the Taguchi method / Principal component analysis along with analytical analysis of Chamis equation. The finite element was adopted in conducting the analysis. Three responses were considered for the laminated composites namely displacement, stress and strain. The findings from the main effects analysis showed that the set of optimum parameters was identified as load applied of 2000N, ply thickness of 0.08 mm, ply quantity of 12 plies, ply angle of 0,90,0 °, material combination of boron/epoxy as well as volume fraction of 65. © 2019 Published under licence by IOP Publishing Ltd.
