Abstract: Curable acrylate-epoxy resin blends comprising an epoxy resin, a crosslinking accelerator, a latent hardener, an acrylate monomer component, and a free radical initiator are provided. Such curable acrylate-epoxy resin blends have a low viscosity and a long pot life. Such curable acrylate-epoxy resin blends are mixed with a fiber component and optionally fillers and then heated to polymerize the acrylate monomer component to form semi-solid molding compounds having a long shelf life. Such molding compounds are molded and further heated to crosslink the epoxy resin to form shaped articles of substantially rigid composite materials.
