    摘要: The present invention relates to an epoxy-resin composition as matrix component for sheet molding compounds (SMC) and/or bulk molding compounds (BMC), comprising a resin component comprising at least one epoxy resin and a hardener component comprising at least one aminoalkylimidazole compound, at least one diazabicycloalkylen compound and at least one latent hardener. In said epoxy-resin composition, the amount of the aminoalkylimidazole compounds used is in the range from 0.007 to 0.025 mol per mole of epoxy groups of the entire composition. The invention also relates to a fiber-matrix-semifinished-product composition (SMC composition or BMC composition) with, as matrix component, the epoxy-resin composition mentioned, and with, suspended therein, short reinforcement fibers with an average length of from 0.3 to 5.0 cm. The invention also relates to the corresponding semisolid fiber-matrix composite, in particular to the semisolid SMC and to the corresponding cured fiber-matrix semifinished product, in particular the cured SMC.
