CURABLE EPOXY RESIN SYSTEMS CONTAINING MIXTURES OF AMINE HARDENERS AND AN EXCESS OF EPOXIDE GROUPS

摘要

A specific epoxy resin system is used to produce a fiber reinforced epoxy resin composite. The epoxy resin system contains polyglycidyl ether of one or more polyphenols. The system also contains a curing agent containing a mixture of aminocyclohexane alkylamine and a polyalkylene polyamine curing agent. The ratio of the epoxy resin group to the amine hydrogen group is 1.05 to 1.50. The epoxy resin system contains a tertiary amine catalyst such as a tertiary aminophenol, a benzyl tertiary amine or an imidazole compound.
