Vibration analysis of carbon and Kevlar fiber reinforced composites containing SiC particles

Özet

This study investigates the vibration-damping properties of Kevlar and carbon fiber reinforced composites with addition of SiC particles within epoxy resin. Experimental modal analysis was performed to extract natural frequency and damping property with aim of the enhancing dynamic performance of the composite system containing SiC particles. A numerical model using ABAQUS software was developed in attempt to predict higher mode frequencies with mode shapes. Results showed that addition of SiC particles with the carbon/epoxy and Kevlar/epoxy composites resulted in a significant effect by means of vibration and damping properties due to interface strength between SiC particles and polymer matrix those influencing elastic properties.
