The Influence of the Different Fiber lay-ups on the Damping Characteristics of Polymer Matrix Composite

P. Nagasankar, S. Balasivanandha Prabu and R. Velmurugan

Abstract:
The dynamic characteristics of glass fiber reinforced polymer composites have been studied for the large number of different lay-ups of fiber, intending to get a better damping without compromising much on the stiffness/frequency values. The better layup has been selected based on the damping and frequency values in mode shapes 1, 2 and 3 and the different layups have then been categorized into three groups (A, B and C). The experimental test was carried out to calculate the natural frequencies and damping factors using Impulse technique (Lab view software-National instruments). The same values have also been evaluated theoretically by the modal analysis performed in FEM software (ANSYS version 11). A good agreement exists between the experimental and theoretical values.
