The Emission of Electrons and Positive Ions from Fracture of Materials.

Abstract

The emission of electrons and positive ions from materials undergoing fracture is investigated. We present a survey of charged particle emission from a number of materials including crystalline insulators, glass, graphite, polymers, and composites. Particular attention is given to fiber-reinforced epoxy systems which yield unique forms of charge emission. Energy distributions of the emitted particles are given for E-glass/epoxy strands, polybutadiene filled with glass beads, and mica. Evidence is presented that interfacial failure and charge separation play important roles in the observed emission. (Author)
