Résumé

The identification of kinetic parameters controlling the crosslinking of Diglycidyl ether of bisphenol/isophorone diamine reactive system was achieved via optimization program (Inverse method) based on Fourier transform near infrared spectroscopy results. The reactivity ratio (k2/k 1) was determined using a new method based on the variation of amine conversion ratio versus epoxy conversion ratio. Gelation and vitrification of the reactive system were also analyzed. Time, temperature, transformation diagram was established to assess the rotational molding of this reactive system.

Poly(methyl methacrylate)-modified epoxy/amine system for reactive rotational moulding: crosslinking kinetics and rheological properties

Article dans une revue avec comité de lecture

MOUNIF, Eskandar; LIANG, Genhai G; COOK, Wayne D; BELLENGER, Veronique; TCHARKHTCHI, Abbas (Wiley, 2009)

The rotational moulding of thermosetting resins is hampered by their low viscosity and the abrupt increase in their viscosity as they polymerize. This study investigates the use of poly(methylmethacrylate) (PMMA) as a ...

AL-JALLAD, Mazen; ATASSI, Yomen; MOUNIF, Eskandar; ARESSY, Matthieu; TCHARKHTCHI, Abbas (Wiley, 2014)

In this work, we present the preparation of polylactic acid (PLLA)/polyaniline (PANI) conductive composite nanofibers mats. They are prepared by bulk oxidative solution polymerization of PANI onto electrospun non-woven ...
Fatigue Damage Initiation of a PA66/Glass Fibers Composite Material

Article dans une revue avec comité de lecture

ESMAEILLOU, Bardia; FEREIRRA, P; BELLENGER, Véronique; TCHARKHTCHI, Abbas (Wiley, 2012)

Fatigue damage initiation of a PA66/glass fiber composite material is studied with interrupted tests carried out with an “alternative bending device” and a small applied strain. During the damage initiation period, no ...
