Multifunctional polymer-based composite materials with weft-knitted carbon fibrous fillers

Loop Length of Plain Single Weft Knitted Structure with Elastane

For decades, scientists have been trying to define relationships among yarn parameters, knitted fabric parameters, and knitting parameters with loop models. Recently, the geometrical loop models have returned to focus as they assist finding the effective parameters which cause dimensional changes during relaxation. Furthermore, they help designing knitted structures for technical applications a...

A composite index to quantify dispersion of carbon nanotubes in polymer-based composite materials

Comparison of submicron-diameter carbon filaments and conventional carbon fibers as fillers in composite materials

This review provides a comparison of submicron-diameter carbon filaments and conventional carbon fibers as fillers in composite materials. Carbon filaments (0.1 mm diameter, catalytically grown) are superior to conventional carbon fibers (discontinuous) as a filler in providing polymer–matrix and cement–matrix composites for electromagnetic performance, but are inferior to the fibers as a fille...

The electrical properties of polymer nanocomposites with carbon nanotube fillers.

The electrical properties of polymer nanocomposites containing a small amount of carbon nanotube (CNT) are remarkably superior to those of conventional electronic composites. Based on three-dimensional (3D) statistical percolation and 3D resistor network modeling, the electrical properties of CNT nanocomposites, at and after percolation, were successfully predicted in this work. The numerical a...

Transverse Thermoelectricity in Fibrous Composite Materials

Transverse thermoelectric elements have the potential to decouple the electric current and the heat flow, which could lead to new designs of thermoelectric devices. While many theoretical and experimental studies of transverse thermoelectricity have focused on layered structures, this work examines composite materials with aligned fibrous inclusions. A simplified mathematical model was derived ...
