Dielectric Monitoring of an Epoxy Cure.
Abstract
This report presents the results of a study to determine the feas-ibility of employing dielectrometry as a monitoring technique to follow the cure of reinforced thermosetting composite materials. The material selected for the investigation was a glass- reinforced, amine-cured epoxy resin. Changes in infrared spectra and DTA thermo-grams were noted and correlated with cure events and the dielectric responses. The peak of the dissipation trace appears directly re- lated to the time of gelation. Correlation of strength data with dielectric responses was inconclusive, indicating that further work is required to utilize dielectrometry in the identification of end-of-cure. (Author, modified-PL)
