Centre for Material Forming (CEMEF), ARMINES-Ecole des Mines de Paris/CNRS, France

Description of the CEMEF:

The CEMEF is a European leader in the field of research on material processing (metals and polymers). Approximately 160 people - including 70 PhD students are performing research designed to get in depth understanding of forming processes. The main expertise is on thermal, mechanical and physical modeling, numerical simulation, processing, physics and chemical physics. In the field of polymers, the main research areas are:

  • Polymers physics: Crystallisation (quiescent, under flow), flow of suspension, polymer rheology, dispersion of porous aggregates.
  • Simulation: Modelling of the main polymer forming processes, software development. Injection molding (Rem3D®), extrusion (Ludovic®), blow molding (TForm®), sheet forming, etc.
  • Surface science: Surface reactivity, adhesive bonding, friction, lubrication, wear.

Description of the polysaccharide research activities:

  • Flow induced morphologies in complex fluids: liquid crystalline polysaccharides, polysaccharide blends, suspensions, colloids.
  • Gels and networks
  • Physics of cellulose: -mechanisms of activation and dissolution of cellulose, thermodynamics (crystallisation, phase transitions, phase diagrammes), rheology, gelation and processing of cellulose solutions, structure of cellulose objects, aerogels.
  • Development of rheo-physical tools: optical microscopy, small angle light scattering, dichroism, birefringence under flow (shear, elongation, complex geometries, counter-rotating system).

Main pieces of equipments:

Environmental SEM, TEM, Tof-SIMS, EDX, XPS, ToF-SIMS, FTIR, WAXS, SAXS, Wetting measurement, DSC, DMA. Transmission optical microscope (with microdrawing and microcompression of films device).

Extruders (single-screw, twin-screw), polymer injection moulding, prototype for stretch blow moulding, internal mixer, apillary/rotational/elongational rheometers, rheo-optical facilities.

3D rugosimeter, tribometers, Traction, high velocity tension-compression, torsion.
