High-pressure rheological analysis of CO2-induced melting point depression and viscosity reduction of poly(?-caprolactone) (2015)
Journal Article

High-pressure rheology has been used to assess the effects of supercritical carbon dioxide (scCO2) on the melting point (Tm) and viscosity of poly (?-caprolactone) (PCL) over a range of temperatures and pressures up to 300 bar over a wide range of sh...

Role of processing history on the mechanical and electrical behavior of melt-compounded polycarbonate-multiwalled carbon nanotube nanocomposites (2015)
Journal Article

This work investigates the effects of primary compounding temperature and secondary melt processes on the mechanical response and electrical resistivity of polycarbonate filled with 3 wt % multiwalled carbon nanotubes (CNT). Nanocomposites were melt... Read More about Role of processing history on the mechanical and electrical behavior of melt-compounded polycarbonate-multiwalled carbon nanotube nanocomposites.

Time-dependent mechanical behavior of human amnion: Macroscopic and microscopic characterization (2014)
Journal Article

Characterizing the mechanical response of the human amnion is essential to understand and to eventually prevent premature rupture of fetal membranes. In this study, a large set of macroscopic and microscopic mechanical tests have been carried out on...

The role of deformation history on stress relaxation and stress memory of filled rubber (2014)
Journal Article

Although the magnitudes of inelastic and viscoelastic effects in filled rubbers are small relative to that of the elastic response, these effects are nevertheless critical in applications such as gaskets, seals and dampers. This study investigates th... Read More about The role of deformation history on stress relaxation and stress memory of filled rubber.

A novel nethod of extraction of blend component structure from SANS measurements of homopolymer bimodal blends (2014)
Journal Article

A new method is presented for the extraction of single chain form factors and inter-chain interference functions from a range of small angle neutron scattering (SANS) experiments on bimodal homopolymer blends. The method requires a minimum of three b... Read More about A novel nethod of extraction of blend component structure from SANS measurements of homopolymer bimodal blends.

Viscoelastic melt rheology and time-temperature superposition of polycarbonate – multi-walled carbon nanotube nanocomposites (2013)
Journal Article

This work investigates the linear and non-linear viscoelastic melt rheology of four grades of polycarbonate melt-compounded with 3 wt% Nanocyl NC7000 multi-walled carbon nanotubes and of the matching matrix polymers. Amplitude sweeps reveal an earlie... Read More about Viscoelastic melt rheology and time-temperature superposition of polycarbonate – multi-walled carbon nanotube nanocomposites.

Time-temperature equivalence in the tack and dynamic stiffness of polymer prepreg and its application to automated composites manufacturing (2013)
Journal Article

A recently developed peel test designed to simulate the automated tape lay-up (ATL) process was used to measure tack and dynamic stiffness of newly developed ATL prepregs. Resin was extracted from the prepreg process before impregnation of the fibres...

A toolbox for parameter-free predictions of solid-state properties of monodisperse glassy polymers with frozen-in molecular orientation (2012)
Journal Article

A toolbox that allows designers to predict the properties of oriented glassy polymers using only existing material constants is constructed from a constitutive model applicable to both polymer solids and polymer melts. Two solid-state properties of p... Read More about A toolbox for parameter-free predictions of solid-state properties of monodisperse glassy polymers with frozen-in molecular orientation.

Large deformations in oriented polymer glasses: experimental study and a new glass-melt constitutive model (2010)
Journal Article

An experimental study was made of the effects of prior molecular orientation on large tensile deformations of polystyrene in the glassy state. A new hybrid glass-melt constitutive model is proposed for describing and understanding the results, achiev...
