Abstract:
1. A carbon/epoxy composition, comprising: a bisphenol-based epoxy compound having at least two epoxy groups; an amine-based curing agent, wherein the amine-based curing agent is a cyano-substituted amine; an imidazole-based curing catalyst; and carbon black, wherein the carbon/epoxy composition comprises about 60 to about 90 weight percent of the bisphenol-based epoxy compound, about 1 to about 30 weight percent of the amine-based curing agent, about 0.1 to about 3 weight percent of the imidazole-based curing catalyst, and about 1 to about 10 weight percent of the carbon black; and wherein a weight ratio of the amine-based curing agent to the imidazole-based curing catalyst is about 10:1 to about 5:1.
