The first studies of nanocomposites were interested in the possibility of the manufacturing of this material as well as the characterization of modified montmorillonite (M.M.T)-loaded polymers. These studies showed the possibility to obtain composites at a nanometric scale. Our objective in this issue is to study clay reinforcements applied to fabrics using different sorts of resins. This approach allows us to avoid impregnation problems, more precisely lack of uniformity while using very low loading rates on isotropic materials. It has already been proved that, by adding clay to the material, the charactersitic improvements were significantly important. The large improvement of polymers mechanical characteristics in the case of the first generation nanocomposites is a good example.

This Special Issue will be devoted to the ways of improving materials’ characteristics (impermeability, fireproofing and shrink resistance etc) by adding clay rather than using resin only as it has been done in the past.

Clay purification and mixing it with resin on an industrial level being a hard task, it is therefore possible and necessary several specialities (geologist in the choice of clay, fluid mechanics in way of mixing, mechanics in setting the mixing propeller’s shape etc.) contribute to make this task easier.

Contributions dealing with medullisation, dielectric, phonic and antistatic properties of these new hybrid materials can also be valuable and will be welcome.
