Free vibration analysis of Hybrid-Composite beams

This study deals with the free vibration analysis of hybrid-composite beams. The combinations for hybrid composites used in the analysis are Carbon/epoxy and Glass/epoxy. The Hybrid-Composite beams have superior material properties than ordinary composites (having fiber and matrix) due to synergistic effect. The free vibration analysis has been carried out on the hybrid composite beams having different fiber orientation angles (θ) from 0° to 90° and aspect ratios (L/h) from 45 to 120 with different boundary conditions by using numerical analysis software (FEA-ANSYS 12.0). In the present work the effects of fiber orientation angles and aspect ratios on natural frequencies and mode shapes of the hybrid composite beams are investigated.
