Abstract

Chemiluminescence anlaysis and high-frequency eddy current testing (HF-ECT) were examined as nondestructive evaluation techniques to assess the hardening degree of epoxy resin in carbon fiber-reinforced plastic. Both techniques showed a correlation with the hardening degree of epoxy resin measured by differential scanning calorimetry. The results also indicated that the application of HF-ECT at frequencies of >50 MHz is suited for hardening degree determination.
