MOCABIO : Processing and characterisation of biocomposite materials


The «Processing and characterisation of biocomposite materials " or MOCABIO platform, co-financed by IMT Mines Alès and the Occitanie Region, aims to develop the research potential of IMT Mines Alès in the field of composite materials based on agro-resources and to constitute a factor of attractiveness and competitiveness for the Occitanie Region. In addition to being a research tool, the platform also supports and accompanies companies and is an educational tool for IMT Mines Alès engineering students, among others.

Bio-composite materials have been attracting considerable interest from the scientific community and the industrial world for several years.  From an application point of view, this interest is motivated by the desire to limit the use of fossil resources, but also and above all by the need to lighten structures in order to reduce fuel consumption in the automobile, rail and maritime transport sectors. However, the industrial use of bio-composites still faces problems of implementation and performance of these materials compared to traditional composites.

MOCABIO is organized into three technical support units:

  • Preparation and Characterisation of Plant Fibres: plant fibre surface treatment systems (automated spraying and pad finishing devices) and characterisation of plant fibres (bulk density, surface properties, dimensional characteristics)
  • Biocomposites Processing (thermoplastic and thermoset): thermocompression, vacuum infusion, co-rotative twin-screw extruders from pilot scale (5kg/h) to laboratory scale (0.5 kg/h), injection moulding, cutting tools.
  • Characterisation of biocomposites: characterisation of fire properties (smoke analysis) and characterisation of fibre/matrix interface (IFSS)
