Abstract

In the present work an experimental study was carried out to study vibration behavior of ABS based Nano composite reinforced by Nano-silica particles. Twin extruder methodology was used here to fabricate the Nano composite samples regarding silica content as variable parameter. The samples were fabricated to be investigated by 3 points bending test in dynamic mechanical and thermal analysis machine. To identify parametric influence, number of 12 experiments has been carried out and the obtained results were discussed according to scanning electron microscopy (SEM) images of the samples cross section. It is found from the results that by increase of silica content up to 2%, the static and dynamic strength of fabricated Nano-composite is significantly enhanced. However, by further increase of silica content it is found that the fabricated sample shows brittle behavior causing reduction of strength properties. It is also found from the results that increase of silica content causes reduction in damping behavior of fabricated composites.
