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.
Claims20
A curable resin composition comprising the reaction product of mixing:
- a) an epoxy resin composition selected from the group consisting of a bisphenol-epoxy resin, a novolac-epoxy resin, a cycloaliphatic resin, or a combination thereof;
- b) a latent hardener comprising a member selected from the group consisting of an anhydride compound, a guanidine compound, or a combination thereof;
- c) an acrylate monomer component;
- d) a crosslinking accelerator comprising a member selected from the group consisting of an imidazole compound, a urea derivative, or a combination thereof;
- and
- e) a free radical initiator.
