A two-component curable epoxy resin system is disclosed. The resin system comprises an epoxy resin component containing at least 80% by weight of a polyglycidyl ether of polyphenol. In addition, the system includes a curing agent mixture that contains primarily polyethylene tetraamine. The system comprises at least one of i) an alkali metal salt, ii) a carboxylic acid-, a carboxylic acid anhydride- or a carboxylic acid ester-substituted phenol compound, and iii) an amino acid as a catalyst. The system has beneficial curing properties useful for making fiber-reinforced composites in a resin transfer molding process. |
