A tube of elastomeric material for an air conditioning system or for other system which is on-board of a motor-vehicle is intended to be fitted over a metal connecting element and to be locked onto the latter by means of a crimping operation that envisages the clamping around the tube of a metal clamping element. The tube includes at least one body made of polymeric elastomeric material supplemented with carbon-based nanofillers wherein an outer surface with one or more piezo-resistive areas is provided, where the polymeric material supplemented with carbon-based nanofillers has been made locally piezo-resistive by means of laser irradiation. The piezo-resistive areas arranged on the body of polymeric elastomeric material of the tube can be used for verifying the correct execution of the crimping operation.

Tube made of elastomeric material for a system which is on-board of a motor-vehicle

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.
