）を用いて１００〜１６０℃の温度の金型にてプレスで
圧縮成形する方法がある。The conventional methods of obtaining a transparent celestial stone-like molded product are the casting method, in which unsaturated polyester compound is injected into the mold at a temperature between room temperature and 80°C, and sheet molding. There is a method of compression molding a compound (hereinafter referred to as SMC) or a bulk molding compound (hereinafter referred to as BMC) using a press in a mold at a temperature of 100 to 160°C.

にてバックアップの必要がある。又１個当たりの成形サ
イクルが長い欠点がある。For the former, products with relatively good transparency have been obtained and are currently on the market, but the obtained products have relatively low strength and have a wall thickness of 101 or more, or are coated with reinforcing material on the back side of the product. It is necessary to make a backup. Another disadvantage is that the molding cycle per piece is long.

中に含まれる繊維補強材や充填剤により透明性が得られ
に（い欠点がある。The latter is superior in mass production due to the high strength of the molded product and the quick molding cycle, but conventional compounds have the drawback of not being transparent due to the fiber reinforcement and fillers contained therein. .

報）。この方法によれば製品の透明性は改善されるが、
強度の点で必ずしも充分ではない。On the other hand, in order to improve the transparency of the product, a method has been proposed in which three-dimensional styrene polymer and glass powder are added to the compound (Japanese Patent Application Laid-Open No. 62-64858). Although this method improves product transparency,
It is not necessarily strong enough.

のである。Problems that the invention aims to solve In recent years, there has been a demand for higher quality and diversification of appearance quality for various products, but this is not the case for SMC and B.
Compression molded products such as MC are no exception. The present invention enables the mass production of molded products with beautiful transparency and high strength by integrally heating and compression molding a compression molded product such as SMC or BMC and a fiber reinforced material using a press machine or the like. This is intended to meet the above market demands.
