Abstract

Composites are the choice in the present decade due to their incredible dominance in so many features. Few of them are great strength to weight ratio and stiffness to weight ratio and high temperature enduring competence. The present study aims at learning the mechanical behavior of hybrid Synthetic fiber composites. They are used in a variety of engineering applications such as airplane wings, helicopter blades, sports equipment’s, medical instruments and turbine blades. Carbon and E-Glass fibers are used as reinforcement, Epoxy resin used as matrix. Specimens were cut from the fabricated laminate according to the ASTM standards for different experiments. After that experiment is performed under Universal testing machine (UTM). Flexural strength & Tensile strength were observed and compared to base values of epoxy polymer to perceive the change in strength. An important element in the dynamic analysis of composite beams is the computation of their natural frequencies and mode shapes. It 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 non-dimensional natural frequencies of the beam are calculated by using ANSYS model of corresponding composite beam.
