Fiber-Optic Raman and Micro-Raman Measurements of Bonding Agents at Interfaces During the Curing Process

Abstract

We have proposed to investigate Raman scattering of epoxies and polyimides in interfacial regions using fiber optic evanescent spectroscopy. These data will be analyzed with chemometric multivariate statistics to provide an understanding of the curing and bonding process in real composites within 0.1 micron resolution and observe inhomogeneities in the curing process at high optical resolution. During this funding period, we have obtained IR and Raman spectra of test matrix materials, made assignments of molecular vibrations, performed laboratory measurements of the curing of the bulk matrices at different temperatures, and begun a principal component analysis of the curing process. Construction of a micro-Raman system was also begun.
