Abstract:

Samples of graphiteepoxy composite from NRL and DRNSRDCCarderock 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
