Multi-Scale Finite Element Modeling of CNT-Polymer-Composites

Abstract

A hierarchical multi-scale approach is used to model a composite consisting of carbon nanotubes and a polymer which can be used as pressure sensor matrix to prevent people from decubitus ulcer. Starting with the modeling of a carbon nanotube and the calculation of its equivalent cylinder properties. Subsequently the cylinders which replace the CNTs are randomly distributed in the polymer such that homogenization techniques leading to the mechanical properties of the composite.
