IMT Lille Douai


Within various contractual frameworks, the TPCIM (Polymers and Composites Technology & Mechanical Engineering) Department contributes to the research & development in the following technological and industrial fields :

  • Processing technologies for plastic & composite materials and industrial parts : study interactions between raw materials, processing conditions (machine and tooling related parameters), quality and performances of manufactured parts, taking into account their lifecycle and recycling ;
  • Reliability and durability of structural parts:  reliable design and durability improvement taking into account manufacturing conditions, applied loads, materials microstructure, parts geometry and environmental effects.

In practice efforts are oriented towards

  • Processing of polymers and particle-reinforced polymers (with fillers, chopped fibers, nano-particles) : experimental analysis, characterization and control of phenomena involved during manufacturing by injection molding, (co-)extrusion molding, thermoforming and rotational molding, with integration of sensors in machines and tooling (sensing & knowledge of phenomena generating quality and/or defects, auto-adaptive process control, parts design and manufacturing optimization...),
  • Processing of structural organic composite materials with continuous fibers experimental analysis, modeling, simulation and active control of coupled phenomena involved during manufacturing, in particular for LCM (Liquid Composite Molding) processes and automated fiber placement (flow, heat transfer, resin thermokinetics, deformation of fibrous media and foam inserts…),
  • Structural mechanics applied to organic or hybrid materials (stochastic mechanics/reliability, creep, fatigue, fracture mechanics, micromechanics, residual stresses...) : implementation of analytical or numerical models and associated computational methods (viscoelasto-plasticity, cohesion or stochastic finite elements, crack-blocks...) coupled to experimental validations (techniques based on ultrasound, acoustic emission, infrared thermometry...),

with a particular attention transversally drawn on :

  • Sustainable development (materials produced from renewable resources such as bioplastics, biofibers/biotextiles, processes with low environmental impact, ecodesign, recycling of production scraps and end-of-life valorization...)

TPCIM department is deeply involved in research and development projects on bio-based materials. It has a strong experience in compounding and processing of bio-based materials. Recently, the department has developed innovative processing method (water assisted extrusion, masterbatch processing of nanocomposites) for the elaboration of  polymer materials (polymer nanocomposites, bio-based polymers, polymer bio-nanocomposites).
