The method allows to monitor a composite material comprising an epoxy resin filled with electrically conductive nanoparticles, wherein at least one electrical property i.e. impedance of the composite material is influenced by being subjected to a mechanical deformation. The method provides for inserting the composite material in an electric circuit emitting an electric signal whose value depends on the electrical property, so that, when the value of the signal overcomes a given threshold value, a warning message is delivered.

Method of monitoring a composite material

This invention relates to a composite material for biomedical applications, in particular dental applications, which possesses self-healing capacity and is able to incorporate a system for the release of active ingredients at the stage of application and use.

Composite material with properties of self-healing and release of active ingredients, for biomedical applications

A process is for preparing a self-healing composite material including a matrix of epoxy polymer in which a catalyst of ring opening metathesis reaction and vessels containing at least one monomer able to polymerize due to a ring opening metathesis reaction are dispersed. The process includes the preliminary step of dispersing at molecular level the catalyst in a mixture containing at least one precursor of the epoxy polymer, and then the steps of dispersing, in the mixture, the vessels and a tertiary amine acting as curing agent of the precursor, and the step of curing the mixture by at least a first heating stage performed at a temperature between 70 and 90&#xb0; C. for a time between 1 and 5 hours, and a second heating stage performed at a temperature between 90 and 170&#xb0; C. for a time between 2 and 3 hours.
