Abstract
Provided is a fiber-reinforced resin pultruded product obtained by molding a fiber sheet, wherein the fiber sheet is a semi-preg sheet in which a thermoplastic resin serving as a matrix for the pultruded product is fused to at least a fiber surface, and, in the fiber-reinforced resin pultruded product, the fiber sheet has been pultruded, and the thermoplastic resin fills an inside of the fiber sheet and spaces between overlapping portions of the fiber sheet and is integrated with the fiber sheet. A molded productis molded by converging a fiber sheetand feeding the fiber sheet into a heating sectionof a pultrusion die; compressing the fiber sheet while heating the fiber sheet to a temperature equal to or above the melting point or a resin flow temperature of the thermoplastic resin in the heating section; molding the fiber sheet in a molding section; cooling the fiber sheet in a cooling sectionto obtain a pultruded product; and pulling the pultruded product out of the pultrusion dieusing pulling rollersand
