Abstract

Compositions and methods for forming epoxy resin systems are provided. In one embodiment, a composition is provided for an epoxy resin system including a liquid epoxy resin component including a liquid epoxy resin and an acrylate monomer, a curing agent component including a compound having an imidazole group and, optionally, a co-curing agent for the compound having an imidazole group comprising a phenolic monomer compound, a branched chain carboxylic acid, and combinations thereof, and a non-aromatic polyol compound. The composition may be used to form composites, such as used in commercial wind turbine blade manufacturing.
