High Performance Damping with Carbon Nanotube-Polymer Composites

Abstract

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.
