The present invention provides a method for producing a prepreg from which a laminate stable and superior in quality can be obtained at low cost without air pollution and with saving of resources and energy, and further provides a method for producing the laminate. That is, the present invention provides a method for producing a prepreg, characterized in that a mechanical energy is applied to a mixture comprising a powdered thermosetting resin and a hardener as essential components to bring about a mechanochemical reaction, the resulting powdered resin composition, as it is, or with addition of a fine powder additive having an average particle size of 0.01-1 mum and uniform mixing of them, is allowed to be present on at least the surface of a fibrous base material, and further provides a method for producing a laminate, characterized in that one or a plurality of the prepregs obtained above are used, if necessary, a metal foil is superposed on both or one side of the prepreg(s), and these are pressed under heating. |
