Zusammenfassung:	PURPOSE: A manufacturing method of prepreg using glass fiber impregnated-prepreg containing artificial marble dust is provided to achieve molded products with enhanced strength in making SMC(Sheet Molding Compound) by increasing the content of glass fiber. CONSTITUTION: A manufacturing method of prepreg using glass fiber impregnated-prepreg containing artificial marble dust is as follows. A resin composition containing artificial marble dust is produced. A resin composition containing artificial marble dust is sprayed on a film. Glass fiber and the resin composition containing the artificial marble dust are sprayed on the top of the film simultaneously. The film sprayed with the resin composition containing artificial marble dust is layered on the top sprayed with glass fiber and pressed.
