摘要： The process for preparing a self-healing composite material comprising a matrix of epoxy polymer, in which a catalyst of ring opening metathesis reaction and microcapsules containing a cyclic olefin having 7 to 40 carbon atoms are dispersed, comprises the steps of: preparing a mixture of a precursor of the epoxy polymer, having at least one oxirane ring, a curing agent chosen from the group consisting of tertiary amines, a Hoveyda-Grubbs II metathesis catalyst reaction, having the formula (I), wherein Ar=aryl having at least one halogen or alkyl substituent and “R=alkyl with 1 to 20 carbon atoms, and microcapsules containing a cyclic olefin having 7 to 40 carbon atoms; and heating the mixture at a temperature comprised between 25 and 130° C. for at least 1 hour, so as to obtain such matrix of epoxy polymer due to a reaction between precursor and curing agent, which reaction does not substantially involve either said catalyst or said microcapsules.
