Quasi real-time monitoring of epoxy resin crosslinking via Raman microscopy

Abstract

Raman spectroscopy has become a powerful analytical tool providing detailed and specific information at a molecular level. This benefit together with rapidity and other features of the method yields an advantage of quasi real time monitoring and measuring the structure changes dynamics. There is no doubt that Raman spectroscopy can be ranked among powerful and useful research and analytical methods applicable across the sciences and also industrial and manufacturing branches. The focus of this paper is in the possibility of using Raman spectroscopy for the process of epoxy resin crosslinking monitoring what involves identification localisation of the principal chemical bonds localisation of epoxy resin in Raman spectra. A mathematical model for a storage temperature of epoxy resin pre-pregs prediction was also proposed.
