Abstract:
In this paper we report, for the very first time, the possibility to UV-crosslink a glass fibre reinforced epoxy
composites. We have demonstrated that the crosslinking reaction proceeds via a radical induced cationic frontal
polymerization (RICFP), where the UV-surface activation of cationic ring opening polymerization is able to
promote the heat front that will activate a thermal initiator in the deeper layers. Because of the very high
velocity of the reaction we could obtain quickly epoxy composites maintaining the good thermo-mechanical
properties.
