Method for manufacturing FRP precursor and method for manufacturing FRP

A method for producing an FRP, comprising:

• providing an aggregate that is in a form of a sheet,
• heating and press-adhering a thermosetting resin film to a surface of the aggregate by pressing the thermosetting resin film to the surface of the aggregate with a pressure roll at a roll pressure in a range of 0.5 to 1.0 MPa, wherein the pressure roll has a temperature in a range of +30° C. to +35° C. relative to a temperature at which a minimum melt viscosity of the thermosetting resin film is exhibited to form an FRP precursor, wherein the heating and press-adhering are conducted while the aggregate, the thermosetting resin film and the pressure roll are under an atmospheric pressure;
• and
• curing the FRP precursor.

A method for producing an FRP, comprising:

• providing an aggregate that is in a form of a sheet, and
• heating and press-adhering thermosetting resin films to each of opposing surfaces of the aggregate by pressing each of the thermosetting resin films to each of the opposing surfaces of the aggregate with pressure rolls at a roll pressure in a range of 0.5 to 1.0 MPa, wherein the pressure rolls have a temperature in a range of +30° C. to +35° C. relative to the temperature at which a minimum melt viscosity of the thermosetting resin films is exhibited, wherein the heating and press-adhering are conducted while the aggregate, the thermosetting resin films and the pressure rolls are under an atmospheric pressure to form an FRP precursor;
