HPLC Monitoring of Graphite-Epoxy Prepreg Aging.

Abstract

A method using high performance liquid chromatography has been developed for the quality control of graphite-epoxy prepregs. The method may be applied both as a standard test method in Military Specifications and as a method for process control. The method is used to monitor compositional changes as the prepreg ages at -13 C, 22 C, and 49 C. Chemical changes in the prepreg are correlated with aging time and process acceptability. (Author)
