Abstract :Present study explores the vibration and damping characteristics of Kevlar and carbon fiber reinforced composites with incorporation of SiC particles within the common matrix of 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 for comparison of experimental results in attempt to predict higher mode frequencies with mode shapes. Results showed that interaction of SiC particles with the carbon or Kevlar/epoxy resulted in a significant effect in terms of vibration and damping characteristics due to interface strength between SiC particles and polymer matrix those influencing elastic properties.
