Jesús Bautista-Del-Ángel, Ana B. Morales-Cepeda, Tomas Lozano-Ramírez, Saúl Sanchez, Shahir Karami, and Pierre Lafleur
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.
