A Simplified Laminar Flow Model for the Pultrusion of Glass Fiber/Polyethylene Terephthalate Commingled Yarns

Advanced Engineering Materials, EarlyView.
A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Flow-induced crystallization of propylene/ethylene random copolymers [PDF]

, 2009
The influence of co-monomer content and processing conditions on the crystallization kinetics of Propylene/Ethylene (P/E) random copolymers is studied using DSC and rheometry.

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Flow-induced crystallization of polybutene-1 and effect of molecular parameters

, 2011
There are two main goals of this thesis: to investigate the flow-induced crystallization behaviour of Polybutene-1 (PB-1 samples, and to study the effects of molecular parameters on the crystallization behaviour While flow-induced crystallization is not ...

Crystallization fractionation of palm oil biodiesel as an alternative for improving its cold flow properties

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
Palm oil biodiesel (POB) has excellent properties as a fuel for engines. However, due to its highly saturated chemical composition, this biofuel presents a faulty performance at temperatures close to the environmental temperature of several Colombian ...

Flow-induced crystallization studied in the RheoDSC device: Quantifying the importance of edge effects [PDF]

, 2015
Flow-induced crystallization is investigated through short-term shear flow experiments on poly(1-butene) in the RheoDSC device. We demonstrate that the DSC signal shows contributions from spherulitic morphology in the center of the sample and oriented ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Flow induced crystallisation of penetrable particles [PDF]

Journal of Physics: Condensed Matter, 2018
Abstract For a system of Brownian particles interacting via a soft exponential potential we investigate the interaction between equilibrium crystallisation and spatially varying shear flow. For thermodynamic state points within the liquid part of the phase diagram, but close to the crystallisation phase boundary, we observe that ...

Precursors and nuclei, the early stages of flow-induced crystallization [PDF]

, 2009
Flow-induced crystallization (FIC) is the main factor determining the properties of melt-processed semicrystalline polymer products. Therefore it has received much attention in scientific research, both experimental and theoretical.
