PROBLEM TO BE SOLVED: To obtain with a low cost a laminate which causes no air pollution, allows resource conservation and has a stable and good quality. SOLUTION: In a preparation process of a prepreg, a powdery composition, obtained by adding a thermosetting resin in the form of powder, which essentially comprises a thermosetting resin and a hardener uniformly mixed, with a thermoplastic resin in the form of fine powder with an average particle size of from 0.01 to 1μm and a hardener or accelerator and uniformly mixing these, is allowed to exist at least at the surface of a sheet-form fiber substrate. In a preparation process for a laminate, one or more of this prepreg is laminated, heated and pressurized. |
