易に得られる製造方法を提供することにある。However, in the composite board obtained by the above-mentioned conventional method, the polyester resin and the phenol resin are different from each other, and therefore, there is a great possibility that separation occurs between the layers. In addition, since the curing properties of the two resins are significantly different, there is a problem that the molding operation by the hand lay-up method is difficult and the molding takes time. Furthermore, it was not possible to obtain a high-strength composite plate in which both the polyester resin and the phenol resin were reinforced with glass fibers. An object of the present invention is to provide a manufacturing method in which a fiber-reinforced plastic composite plate having excellent mechanical strength, heat resistance, and flame retardancy can be easily obtained in a short time.

Usually, the range of 130 ° C to 150 ° C is preferable, and 140 ° C is particularly preferable from the curing characteristics of the phenol resin and the polyester resin. The pressure is usually set to 40 to 50 kg / cm 2 until the pressure of the phenol resin SMC is released, and 50 to 100 kg after the mold is opened and the polyester resin SMC is placed.
It is preferable to increase the pressure to kg / cm 2 . Mold opening time is 5
A range of ~ 15 seconds is preferred. The molding time is set in accordance with the curing time of the phenolic resin SMC. For example, when the thickness of the composite plate is 3 mm, it is about 4 minutes.
