Title of the work to be developed: "Development of advanced energy absorbing composites based on natural cork, shear thickening fluids and microfluidics (CorkSTFluidics)".

CorkSTFfluidics are composites reinforced by shear thickening fluids and microfluidics networks. They are called to mark the beginning of a new era of composite materials, which consist of the combination of three areas of knowledge: microfluidics, complex fluids and solid mechanics.

Thus, the resulting composites are made of a sheet of micro-agglomerated cork engraved by laser with a network of closed microchannels, which are filled with a shear thickening fluid and covered with another sheet of micro-agglomerated cork. The selection of the geometry and dimensions of the microfluidic network are optimized numerically in combination with the rheological properties of the complex fluid and the mechanical properties of the solid material, in order to maximize the mechanical performance of the composite for each particular application and environmental conditions. 

The present technology allows the customization of a composite on demand upon the knowledge of the mechanical response required for a particular application (energy absorption under impact, vibration, etc.), either as core or skin material, or both simultaneously. 

The results we have obtained so far have been submitted for a patent, an article and have been disseminated to the general public in different ways:


I'm sorry, but this is all I can tell so far. I am just starting. Although more information will be posted soon, if you want to know more about this research line and you cannot wait for the next post...just contact me.
