The overall goal of this research project is to investigate the characteristics of carbon nanotube CNT filler-based polymers and provide guidelines to advance the state of the art of structural damping enhancement utilizing CNT fillers. Our major efforts have been focused on 1 To perform tests to observe the damping effect of composites with CNT fillers 2 To develop a micromechanical constitutive model to analyze the effects of the stick-slip motion of the filler-filler and filler-resin interactions on the total loss factor of composite with aligned and randomly oriented, dilute nanoropes 3 To simultaneously analyze the effects of the viscoelastic resin together with the stick-slip motion of the filler-filler and filler-resin interactions on the total loss factor of composite with dilute nanoropes 4 To utilize molecular dynamics MD simulations to analyze the interfacial strength at the filler-filler and filler-resin interface and 5 To develop methods for nanofiller alignment in composites.
