Effect of Different Hybrid Configurations on the Static and Vibration Analysis of Perforated Composite Laminates

The proposed research paper aims to examine the effects of different hybrid configurations and cutouts on the static and dynamic analysis of composite laminates. The study employs a 9-noded heterosis FE model to analyze hybrid composite laminates consisting of carbon and glass fibers arranged in various stacking sequences. The effect of varying cutouts on the stiffness and frequency of the laminates is also evaluated. The static analysis focuses on the laminate’s deformation under different stacking sequences, while the vibration analysis evaluates the laminate’s natural frequencies and mode shapes. The results obtained are compared to investigate the effect of different hybrid configurations and cutout sizes on the laminate’s performance. The research findings reveal that the hybrid configurations improve the stiffness and natural frequency of the laminates, while the cutout size has a significant impact on the vibration characteristics of composites. The study’s findings are also expected to provide insights into optimizing the hybrid composite laminates’ design for specific applications, where weight reduction and high strength-to-weight ratios are essential.
