PURPOSE:To obtain a fiber-reinforced thermoplastic resin structual body at a high productivity which is superior in adhesion between a reinforcing fiber and thermoplastic resin and has excellent mechanical properties. CONSTITUTION:This is a method for manufacturing a fiber-reinforced thermoplastic resin structual body wherein continuing reinforcing fiber is coated and impregnated with molten thermoplastic resin while pulling a continuing reinforcing fiber. This is a method for manufacturing the fiber-reinforced thermoplastic resin structural body wherein (a) directly before coating and impregnation of the reinforcing fiber with the molten thermoplastic resin, the reinforcing fiber is preheated at a teperature of at least the melting point of the thermo- plastic resin, (b) after the rinforcing fiber is coated with the molten thermoplastic resin, the same is passed through by bringing into contact with a protrusion in a passage having at least eight protrusions affanged alternately and vertically, which are heated at the melting point of the thermoplastic resin or higher. |
