主权项

1. A pre-molding article comprising
i) a polymer phase including one or more thermoset resins, one or more thermoplastic resins, and one or more cross-linking agent suitable for cross-linking the thermoset resin; and ii) an inorganic phase, wherein the inorganic phase is present at a concentration of about 30 volume percent or more based on the total volume of the polymer phase and the inorganic phase; wherein the polymer phase is a continuous phase; the weight ratio of the one or more thermoset resins to the one or more thermoplastic resins is about 0.1 or more; and the polymer phase includes thermoset resin domains having at least 70% by volume thermoset resin and thermoplastic resin domains having at least 70% by volume thermoplastic resin.
