Latent epoxy resin formulations are suitable for liquid impregnation processes for production of fiber composite materials.

Latent epoxy resin formulations for liquid impregnation processes for production of fibre composite materials

An epoxy resin composition including A) at least one epoxy compound and B) a hardener composition including B1) 0.1%-100% by weight of 2-(3-(aminomethyl)-3,5,5-trimethylcyclohexyl)propane-1,3-diamine, and B2) 99.9%-0% by weight of at least one further diamine and/or polyamine, where the stoichiometric ratio of the epoxy groups of A) and the number of active hydrogen atoms of the functional groups of B) varies from 1:2 to 2:1.
