Effects of Fiber Type and Number of Layers on Modal Analysis of Laminated Composite Plates

Abstract

The goal of this study is to examine the effects of fiber type and number of layers on modal analysis of laminated composite plates using finite element and Taguchi methods. Modal analysis was carried out by finite element software ANSYS in accordance with L9 orthogonal array which has two control factors such as fiber types and number of layers. Optimal levels of fiber types and number of layers were determined using analysis of Signal-to-Noise ratio, while importance levels and percentage effects of control factors were performed using analysis of variance at 95% confidence level. According to results obtained from this study, the maximum fundamental natural frequency value was calculated using boron-fiber-reinforced laminated composite plates with three layers. Numerical and statistical results obtained from this study can be useful to select the appropriate fiber types and number of layers for laminated composite plates.
