PROBLEM TO BE SOLVED: To obtain a good laminate not causing air pollution, capable of saving resources and having a stable quality at a low cost. SOLUTION: This method for producing a prepreg comprises giving mechanical energies to powdery components, respectively, consisting essentially of a powdery thermosetting resin and a powdery curing agent, to cause a mechanochemical reaction and subsequently disposing the obtained powdery resin composition at least on the surface of a sheet-like fiber substrate as such or after homogeneously mixed with a finely powdery additive having an average particle diameter of 0.01-1μm. The method for producing a laminate comprises laminating one or more of the prepregs and subsequently heating and pressing the laminated prepregs. |
