The project DESTRIER proposes to increase the life and service duration of a wide family of products through the development of innovating soft surfaces offering tribological properties (friction, adhesion,…) that optimally fulfill various specifications set a priori. For that, we will build a series of demonstrators related to different tribological functions, as obtained thanks to an original design method, developed very recently in LTDS. This method enables, starting with a desired tribological behavior law, identification and fabrication of a surface topography that realizes this law. The collaboration with LaMCoS will enable access to a wider range of tribological laws, through the use of advanced multi-scale inversion methods. The collaboration with Manutech-USD will enable fabrication of surface asperities both smaller and with more complex geometries, using laser texturing. Those two additional competences will enable accessing and studying laws that are known to be difficult to obtain, or even that do not exist in nature, on realistic surfaces. We will target, among others, multi-functional surfaces (e.g. simultaneously but independently controlled friction law and adhesion force ; anisotropic friction or interfacial stiffnesses). Such surfaces will be of major interest for all applications in which soft materials (elastomers, gels, artificial skins) are involved in functional contact interfaces. The industrial domains at stake include haptics, soft robotics, sports equipment, soft lithography/microcontact printing. The project will settle our consortium as an international leader on the topic of the design of surfaces with controlled tribological functions. It will also enable the necessary increase in TRL to reach the development of efficient industrial partnerships at the end of the project.
