PURPOSE:To obtain a FRP molded product free from the mutual separation of its components and from the leakage of water by roughening the surfaces of the FRP molded product compounds, coating the roughened surfaces with a specific surface resin an subsequently coating a specified bonding resin on the surface resin-coated surfaces. CONSTITUTION:The end surfaces of FRP molded components are faced to each other, and a bonding resin 7 containing an unsaturated polyester resin or epoxyacrylate resin as a main component is coated over the ends of both the mutually faced molded product compounds to bond the molded product components to each other. Therein, the end surfaces of bonded components are sized to form roughened surfaces, which are coated with a surface resin 8 mainly comprising an unsaturated polyester resin or epoxy acrylate resin to convert the surfaces into a surface 8' for bonding to the bonding resin 7. |
