Abstract

Provided are a method for producing an FRP precursor and a device for producing an FRP precursor, wherein the method and the device have a good productivity, and under a normal pressure, enable filling of a resin into a bulk gap of an aggregate as well as prevent the resin from spouting out from an edge portion thereof. The method for producing the FRP precursor is to produce the FRP precursor by melt-adhering each of a pair of thermosetting resin filmsto each of both surfacesandof an aggregatethat is in a form of a sheet, the method comprising: an aggregate's surface heating process to heat aggregate's both surfaces, i.e., the both aggregate's surfacesandof the aggregate, and a film press-adhering process to obtain the FRP precursor wherein under a normal pressure, one aggregate-side film surfaceof the pair of the filmsis press-adhered to one surface of the heated both aggregate's surfaces, and another aggregate-side film surfaceof the pair of the filmsis press-adhered to another surface of the heated both aggregate's surfaces.
