The Effects of High Intensity Electrical Currents on Advanced Composite Materials

Abstract

The objective of this investigation was to perform a research study to investigate high intensity electrical current flow and resulting degradation in advanced boron/epoxy and graphite/epoxy composites. Means of providing internal protection from such damage are investigated. Necessary electrical, physical, chemical, microstructure, and mechanical analyses and tests were performed to permit modeling of electrical current flow process and damage mechanisms. Photomicrographic analysis, electron microprobe, scanning electron microscope, x- ray diffraction, tensile tests and physical property measurements were included. (P.S.-PL)
