PURPOSE: To provide a method for producing a fiber composite material capable of homogenizing product strength.

CONSTITUTION: The subject method is a method for producing a fiber composite material in which a thermoplastic resin is impregnated into matlike materials 1 consisting essentially of inorganic fiber. The following steps are successively performed. A laminating step for sandwiching a thermoplastic resin 2 between the above-mentioned matlike materials 1, carrying out needle punching treatment, simultaneously laminating thermoplastic resin films 4 to the surface on at least one side of the resultant sandwiched substance 3 and forming a laminate 5; a heating step for heating the aforementioned laminate 5 to a temperature above the melting temperature of the above-mentioned resin component and melting the resin component; a compressing step for compressing the laminate 5 in the molten state; an extending step for extending the aforementioned laminate 5 in the state of the melted resin component and increasing the thickness of the laminate 5 and a cooling step for cooling the extended laminate 5.
