Vibration Analysis of Carbon Fiber and Glass Fiber Composite Beam

Abstract

Composite materials are widely considered nowadays for several kinds of structural applications. In the analysis of the beam, particularly for a composite using experimental or numerical method, it is quite challenging in comparison with the regular conventional materials. Hence, in the present work, carbon fiber and glass fiber beam are considered for vibration analysis of composite beam. In the numerical modeling, three aspect ratios (i.e., L/H) in the range of 100–150 are considered with multilevel orientations (i.e., [0/0]3, [45/90]3, [90/0]3 [0/0]4, [45/90]4, [90/0]4). Two boundary conditions (cantilever, simply supported) are considered for the beams. From the numerical analysis, it is observed that glass fiber composite beams have a higher natural frequency in comparison to carbon fiber composite beam.
