<p>PROBLEM TO BE SOLVED: To provide a method for producing a fiber-reinforced plastic, in which defects such as a poor outer appearance, meanders of a fiber and warpage can be restrained from being developed in the fiber-reinforced plastic to be obtained.SOLUTION: The method for producing the fiber-reinforced plastic comprises the steps of: impregnating a reinforcing fiber with a thermoplastic resin to obtain a prepreg base material; piling up two or more pieces of the prepreg base materials to obtain a prepreg laminate; heating the prepreg laminate in a heating device 100; and cooling/pressing the heated prepreg laminate in a cool press machine 130. A temperature Th(°C) of the prepreg laminate 10 when heated and a temperature Tc(°C) of the prepreg laminate 10 when cooled/pressed are controlled so that the inequalities: Tm+10≤Th≤Tm+100, Tm-100≤Tc≤Tm-10 and 20≤Th-Tc≤110 (on condition that Tm(°C) is the melting point of the thermoplastic resin or the glass transition temperature thereof when the thermoplastic resin has not the melting point) are satisfied.</p> |
