The research program GReC aims to develop multifunctional composites with silicon based-ceramic matrices reinforced by graphene, which are compatible with environmental-friendlier water-based lubricants.

 

Controlling friction- and wear-related phenomena in mechanical systems is a critical issue for the scientific and industrial communities because it impacts their energy efficiency and therefore their ecological footprint. The development of novel materials, combining both mechanical and functional properties and a good compatibility with environmentally-friendly water-based lubricants, can provide energy efficiency and environmental sustainability across a large number of industries.

The research program GReC aims to develop multifunctional composites with silicon based-ceramic matrices reinforced by graphene. An original, one-step, in situ chemical

deposition process will permit the preparation of nanocomposite materials with

graphene sheets homogeneously dispersed inside the ceramic matrix. The tribological

performances of the composites (friction, crack resistance) will be evaluated in different environments and investigated as a function of the composite microstructures.
