Study the damping and vibrational properties of polycarbonate reinforced ZrO2

In this paper, the effect of nano zirconia particles on damping characteristics polycarbonate composites was investigated experimentally. The were added to matrix with five different weight percentage (wt %). Polycarbonate Nanocomposites filled pristine and modified ‎Zirconium dioxide prepared by simple melt compounding. All samples ‎were an injection molding process. studied before after damage. Damage process done high velocity impact. half-power bandwidth method used experimentally estimate ratio. experiments designed based impulse actuator signal generated ‎shaker, responses recorded using accelerometer sensors. results showed that properties composite increased adding nanoparticles 3 wt% decreased gently for upper content nanoparticles. Transmission electron microscopy (TEM) pictures investigate distribution a homogeneous mixture nanocomposites strong bonding between vibration. Finally, experimental modal analysis test high-velocity impact damage defection composites. great decline in vibration increase properties.
