Abstract

Gold nanorods exhibit irreversible shape change induced by temperatures typical for epoxy curing. This article shows that correlations between degree of cure of a commercially available, structural aerospace epoxy and spectral response of gold nanorods can be made. After initial correlations were obtained, gold nanorods were used to follow degree of cure in three notional cure schedules, both as planned and two 'error' cases where curing did not progress as intended. With further research, this concept could be extended to high spatial resolution cure monitoring as well as accumulative use data for life prediction and sustainment applications.
