Abstract:
The present invention relates to a method for fabricating a fiber-reinforced plastic composite material covered with sheet metal skins, the method comprising: a sheet metal skin pre-stamping step for stamping two sheet metals, thereby fabricating an upper sheet metal skin and a lower sheet metal skin; a pressing process preparation step for making preparations by mounting the upper sheet metal skin and the lower sheet metal skin on a press machine and positioning, between the upper sheet metal skin and the lower sheet metal skin, an inner material which is a thermosetting resin material having a reinforcement fiber mixed therein; a sheet metal skin pre-heating step for heating the upper sheet metal skin or the lower sheet metal skin; and a pressing process for press molding the thermosetting resin having a reinforcement fiber mixed therein, which is interposed between the upper sheet metal skin and the lower sheet metal skin, wherein, before or after the upper sheet metal skin and the lower sheet metal skin are mounted on the press machine, a thermosetting adhesive is applied on the lower surface of the upper sheet metal skin and the upper surface of the lower sheet metal skin, and in the pressing process, the thermosetting adhesive applied on the lower surface of the upper sheet metal skin and the upper surface of the lower sheet metal skin is cured and adhered at the same time as the thermosetting resin having a reinforcement fiber mixed therein is molded and cured.
