Fracture in Carbon-Epoxy Composites.
Abstract
Samples of graphite/epoxy composite from NRL and DRNSRDC/Carderock were analyzed optically and electrically. The NRL samples, which were notched, were fractured by tension while their electrical conductivity was monitored. The results showed that initial fracture was matrix cracking rather than fiber breakage. A fracture model based on a hierarchy of elementary failure mechanisms is being formulated. (Author)
