Experimental Investigation and Free Vibration Analysis of Hybrid Laminated Composite Beam Using Finite Element Method

Abstract

The present study aims at learning the mechanical behavior of Hybrid Synthetic fiber composites. The laminated composite beams are basic structural components used in a variety of engineering structures such as airplane wings, helicopter blades and turbine blades as well as many others in the aerospace, mechanical, and civil industries. An important element in the dynamic analysis of composite beams is the computation of their natural frequencies and mode shapes. This is important because composite beam structures often operate in complex environmental conditions and are frequently exposed to a variety of dynamic excitations. Free vibration analysis was carried out for identifying the natural frequencies. A dynamic analysis is carried out which involves finding of natural frequencies and mode shapes for different stacking sequences. Finally the nondimensional natural frequencies of the beam are calculated by using ANSYS model of corresponding composite beam. Hybrid Composite Beams are made using the hand-lay-up process. E-Glass fiber and Carbon fiber are used as reinforcement in the form of Unidirectional and bidirectional fabric and Epoxy resin as matrix for the composite material of beams. Experiments are performed under Universal testing machine (UTM) and 3-point Bending Test. Flexural strength & Tensile strength were observed and compared to base values of epoxy polymer to perceive the change in strength. From the results, the influence of fiber orientations on the natural frequencies is investigated. Numerical analyses are carried out to study vibration behavior of composite laminated beams using ANSYS 15 software.
