Abstract 1. A PROCESS FOR MOLDING A PRODUCT FROM A CURABLE, MOLDABLE RESIN COMPOSITION IN A MOLD THEREFOR, COMPRISING: (A) LINING SAID MOLD WITH A DRY, FLEXIBLE PREFABRICATED GEL COAT COMPRISING A LAYER OF A PARTIALLY CURED, CURABLE, EPOXY RESIN FORMED BY REACTING AN EPOXY RESIN HAVING A MOLECULAR WEIGHT IN THE RANGE OF 350 TO 950 AND AN EPOXY EQUIVALENT IN THE RANGE 150 TO 550 WITH A POLYDIBASIC ACID POLYANHYDRIDE HAVING AT LEAST FOUR ANHYDRIDE REPEATING UNITS IN A POLYMER CHAIN, AND A FIBROUS REINFORCING MEDIUM OF THERMOPLASTIC RESIN COMPATIBLE WITH THE EPOXY RESIN, SAID EPOXY RESIN CONTAINING IN PARTS BY WEIGHT 50-85 PARTS OF SAID POLYDIBASIC ACID POLYANHYDRIDE, 10-25 PARTS OF FUMED ALUMINA, AND 0.5-5 PARTS OF AN ACCELERATOR PER 100 PARTS OF SAID RESIN, (B) ADDING TO SAID MOLD A MOLDABLE RESIN COMPOSITION SELECTED FROM THE GROUP CONSISTING OF EPOXY RESINS AND POLYESTER RESINS, (C) HEATING THE DRY GEL COAT TO SOFTEN THE THERMOPLASTIC FIBERS AND PARTIALLY CURED EPOXY RESIN OF THE GEL COAT, FLOWING AND SHAPING THE SOFTENED THERMOPLASTIC FIBERS AND PARTIALLY CURED EPOXY RESIN TO A DESIRED SHAPED DETERMINED BY THE MOLD, AND (D) FINALLY CURING THE PARTIALLY CURED EPOXY RESIN OF THE GEL COAT.
