4 January 2017
Processing poly(lactic acid) with low concentrations of silver using a twin-screw extruder leads to nanocomposites with enhanced crystallinity and improved mechanical properties.

Starve-fed single-screw extrusion of polymer blends

Krzysztof J. Wilczyński, Adrian Lewandowski, and Krysztof Wilcyński
21 November 2016
In contrast to flood-fed extrusion, two distinct stages of melting are observed during starve-fed extrusion and a novel melting mechanism is thus proposed.

Frictional heating of extruded polymer melts

José Pérez-González, Héctor S. Zamora-López, and Benjamí-n M. Marí-n-Santibáñez
8 June 2016
Rheo-particle image velocimetry and thermal imaging results show that frictional and viscous heating act synergistically to produce significant temperature increases when a melt is extruded under slip conditions.

Predicting the extent of resin infiltration in pin-assisted pultrusion

Thanasis D. Papathanasiou and Nickolas D. Polychronopoulos
8 March 2016
A simple explicit model is proposed, based on analysis of computational results that show the extent of resin infiltration in a pin-assisted pultrusion process scales with a novel dimensionless group.

Ultrasonic twin-screw extrusion for polypropylene/carbon nanotube nanocomposites

Jing Zhong and Avraam I. Isayev
19 February 2016
An innovative ultrasonic twin-screw extruder with different screw designs is applied to improve the dispersion efficiency of carbon nanotubes in polypropylene.

Integrated computer model for intermeshing counter-rotating twin-screw extrusion

Krzysztof Wilczyński, Adrian Lewandowski, Andrzej Nastaj, and Krzysztof J. Wilczyński
29 December 2015
Metering, melting, and solid conveying are considered in an experimentally verified simulation approach for the calculation of melting, pressure, temperature, and fill factor profiles.

Investigating two electrospinning mass transfer mechanisms

Danny J. Y. S. Pagé, Jennifer Scott, and Siavash Sarabi-Mianeji
12 October 2015
Whipping and splitting—favored by separate processing conditions—result in different fiber diameters and diameter distributions, and can be identified by the measured current during processing.
