Investigation of Kevlar and Basalt fiber hybridization on vibrational characteristics of composite plates

The study of vibrational characteristics of plates, specifically composite plates, has gained significant importance in contemporary and cutting-edge industries involved in industrial plate manufacturing. This paper investigates the vibrational behavior of composite plates made of Kevlar, basalt, and a hybrid combination of Kevlar and basalt fibers embedded in an epoxy matrix. The investigation was carried out through experimental methods utilizing the D3560 analyzer device. Furthermore, in order to ensure the reliability of the findings, the experimental data were simulated and compared with finite element modeling using the ABAQUS software. The results demonstrate that hybridizing the fibers in the first and second modes leads to an increase in the natural frequency compared to pure Kevlar, while the hybridization effect compared to pure basalt has a negative impact. However, in the third to fifth modes, the layered arrangement shows an increase in the natural frequency compared to pure Kevlar and pure basalt. The experimental results obtained and the simulated ones in the finite element software exhibit a consistent trend.
