    Abstract: The invention relates to an epoxide resin composition as a matrix component for sheet molding compounds (SMCs) and/or bulk molding compounds (BMCs), comprising a resin component comprising at least one epoxide resin and a hardener component comprising at least one imidazole compound and at least one latent hardener. In said epoxide resin composition, the amount of the imidazole compounds used lies in a range of 0.007 to 0.025 mol per mol of epoxide groups of the entire composition, and the total amount of optionally contained primary amine groups does not exceed a proportion of 0.09 mol per mol of epoxide groups of the entire composition. The invention further relates to a fiber-matrix semifinished-product composition (SMC or BMC composition), comprising said epoxide resin composition as a matrix component and short reinforcing fibers suspended therein and having an average length of 0.3 to 5.0 cm. The fiber-matrix semifinished-product composition can be produced by mixing the constituents, whereupon the composition thickens. The thickened product thus obtained (semisolid fiber-matrix semifinished product) is characterized by a comparatively short maturing time and comparatively long handleability. The invention further relates to the corresponding semisolid fiber-matrix semifinished product, in particular the semisolid SMC, and the corresponding hardened fiber-matrix semifinished product, in particular the hardened SMC. Finally, the invention further relates to a screening method for identifying epoxide-resin-based compositions that are suitable for use as a thermosetting matrix for the production of SMCs.
