Abstract
Fiber reinforced epoxy resin composites are produced using a specific epoxy resin system. The epoxy resin system contains at least one polyglycidyl ether of a polyphenol. The system also contains a hardener that contains a mixture of aminocyclohexanealkylamine and polyalkylene polyamine hardeners. The ratio of epoxy resin groups to amine hydrogen groups is from 1.05 to 1.50. The epoxy resin system contains a tertiary amine catalyst such as a tertiaryaminophenol, a benzyl tertiary amine or an imidazole compound.
