A Method of Obtaining a True Infrared Spectrum of the Epoxy from a Cured Fiberglass-Epoxy Composite

Abstract

A method of separating epoxy from a cured fiberglass-epoxy composite has been developed and evaluated. This separation is necessary if a true infrared spectrum of the epoxy is to be obtained for the purpose of characterization. The method consisted of separating two materials of different specific gravities with a liquid of intermediate specific gravity-the concept of differential flotation. Infrared spectra of there differently prepared specimens of the same lot of prepreg composite were compared. The resulting infrared spectra prove the feasibility of this approach to cured fiberglass-epoxy characterization.
