Abstract: An elastic support for on-board suspension systems of a motor-vehicle includes at least one body formed of polymeric elastomeric material supplemented with carbon-based nanofillers. An outer surface is provided with one or more piezo-resistive areas where a polymeric material supplemented with carbon-based nanofillers has been made locally piezo-resistive by laser irradiation so as to define one or more electric deformation sensors configured to detect the load applied on the elastic support.

Abstract: A method for measuring a degree of cross-linking of a component of elastomeric material obtained as a result of a hot-forming process, includes a preliminary calibration step in which a plurality of samples are provided, made of the same material as the component. The samples have different degrees of cross-linking following respective hot-forming processes conducted for different periods of time. The preliminary calibration step includes providing a measuring device having an electrical circuit, in which a voltage generator is arranged in series with metal contacts configured to selectively receive a sample, and an ammeter, positioning a sample between said metal contacts, providing a predetermined voltage value, and detecting the corresponding current value by means of said ammeter. The aforesaid steps are repeated for each sample so as to obtain a calibration map that associates a given degree of cross-linking of the material constituting said component with each determined value of electrical conductivity.
