A COMPOSITE MATERIAL WHICH IS SELF-REPAIRING EVEN AT LOW TEMPERATURE

摘要

The composite material comprises a thermosetting polymer matrix in which a ring-opening metathesis reaction catalyst, and microcapsules containing a reactive monomer which can polymerize as a result of a ring-opening metathesis reaction and subsequently cross-link, are dispersed. The reactive monomer is 5-ethylidene-2-norbornene and the catalyst is preferably selected from the group constituted by Grubbs and Hoveyda-Grubbs catalysts.
