    • Kinetic modelling of radiochemical ageing of ethylene-propylene copolymers 
      Article dans une revue avec comité de lecture
      VERDU, Jacques; MONCHY-LEROY, Carole; ccCOLIN, Xavier; ccRICHAUD, Emmanuel (Elsevier, 2010)
      A non-empirical kinetic model has been built for describing the general trends of radiooxidation kinetics of ethylene-propylene copolymers (EPR) at low γ dose rate and low temperature. It is derived from a radical chain ...
    • Response of a carbon-black filled SBR under large strain cyclic uniaxial tension 
      Article dans une revue avec comité de lecture
      BRIEU, Mathias; DIANI, Julie; MIGNOT, Christian; MORICEAU, Christophe (Elsevier, 2010)
      A carbon-black filled SBR was submitted to various uniaxial tension cyclic tests in order to study its cyclic softening. Stress-softening and stretch creep were monitored during stretch-control tests and ratcheting tests, ...
    • Ring tests on high density polyethylene: Full investigation assisted by finite element modeling 
      Article dans une revue avec comité de lecture
      LAIARINANDRASANA, Lucien; DEVILLIERS, Clémence; OBERTI, Sandrine.; GAUDICHET, E; LUCATELLI, Jean Marc; ccFAYOLLE, Bruno (Elsevier, 2011)
      In order to characterize the mechanical behavior of HDPE pipes, the ASTM D 2290-04 standard recommends carrying out tensile tests on notched rings, cut out from the pipe. This very simple test is also utilized to investigate ...
    • Kinetics of chlorine-induced polyethylene degradation in water pipes 
      Article dans une revue avec comité de lecture
      DEVILLIERS, Clémence; LAIARINANDRASANA, Lucien; OBERTI, Sandrine; GAUDICHET-MAURIN, Emmanuelle; ccFAYOLLE, Bruno (Elsevier, 2011)
      The presence of chlorine in drinking water supplies in many countries creates the undesirable side effect of causing a relatively under investigated degree of polymer degradation in the polyethylene pipes used for transport. ...
    • Kinetic analysis and modelling of PET macromolecular changes during its mechanical recycling by extrusion 
      Article dans une revue avec comité de lecture
      NAÏT-ALI, Linda K.; BERGERET, Anne; ccCOLIN, Xavier (Elsevier, 2011)
      The rheometer cavity has been chosen to analyze, in carefully controlled exposure conditions, the PET macromolecular changes generated during its mechanical recycling by extrusion. Isothermal ageing experiments at 280 °C, ...
    • Barrier properties of poly(lactic acid) and its morphological changes induced by aroma compound sorption 
      Article dans une revue avec comité de lecture
      COLOMINES, Gael; DUCRUET, Violette; COURGNEAU, Cécile; GUINAULT, Alain; DOMENEK, Sandra (Wiley, 2010)
      The barrier properties of poly(lactic acid) (PLA) play a key role in food packaging applications. For their optimization, the influence of crystallinity on the barrier properties of PLA and the interaction of PLA with the ...
    • Analysis of the Structure-Properties Relationships of Different Multiphase Systems Based on Plasticized Poly(Lactic Acid) 
      Article dans une revue avec comité de lecture
      COURGNEAU, Cécile; DOMENEK, Sandra; GUINAULT, Alain; AVÉROUS, Luc; DUCRUET, Violette J. (Springer Verlag, 2011)
      Poly(lactic acid) is one of the most promising biobased and biodegradable polymers for food packaging, an application which requires good mechanical and barrier properties. In order to improve the mechanical properties, ...
