Abstract:
1. A method of producing a mold for reinforced thermoset materials comprising: applying a flexible pattern over a first die surface; applying a flexible thermoplastic splash mold material over the flexible pattern; apply at least one of pressure or vacuum to the flexible thermoplastic splash mold material thereby causing the flexible thermoplastic splash mold material to conform to the shape of the flexible pattern; cooling the splash mold material to form a substantially rigid second die surface; removing the flexible pattern from the substantially rigid second die surface to expose a second die surface; applying an uncured thermoset material at the second die surface; applying the thermoplastic splash mold material over a third die; apply at least one of pressure or vacuum to the flexible thermoplastic splash mold material thereby causing the uncured thermoset material to conform to the shape of the second die surface; curing the uncured thermoset material under heat and pressure to form a cured thermoset material; and removing the substantially rigid second die surface from the cured thermoset material.
