Abstract
A method of evaluating dispersion degrees of mixed epoxy resins includes, first, obtaining a resin mixture by mixing a plurality of aromatic epoxy resins, and taking a plurality of measurement samples from a plurality of sites of the resin mixture. The measurement samples are spectroscopically analyzed to obtain the spectra, and a plurality of common functional group peaks in the spectra are selected. The absorbances of the selected peaks are standardized to obtain absorbance ratios, based on the absorbance of a standard peak, in each of the spectra. Then, the standard deviations of the absorbance ratios of the selected peaks are calculated between the measurement samples. The maximum value of the obtained standard deviations is compared with a predetermined threshold value to evaluate the dispersion degrees of the aromatic epoxy resins.
