Multiscale Design and Manufacturing of Hybrid DWCNT-Polymer Fibers

Abstract

This project was aimed to develop advanced fibers with high strength, stiffness, and toughness with low weight and cost for next-generation flexible armors. Toward this goal, this MURI team performed multiscale testing of hierarchical yarns; fabricated directly spun and mat derived yarns for comparative studies of static mechanical properties and structural characterization; applied molecular mechanics and coarse-grained modeling of carbon nanotubes and bundles to predict shear interactions, interface properties, and load sharing; explored the effect of carbon nanotubes on the mechanical properties of graphene oxide paper as a macroscopic model to study the interface between adjacent carbon-based nanofillers; and optimized polyacrylonitrile-nanofibers and nanofibers templated with graphene oxide nanoparticles.
