Disclosed is a method for producing long-fiber-reinforced thermoplastic resin pellets, comprising pultruding a plurality of reinforced fiber bundles in a molten thermoplastic resin while twisting the plurality reinforced fiber bundles to form a strand in which the reinforced fibers are coated with the thermoplastic resin, and cutting the strand to a predetermined length to form pellets, wherein the strand is pultruded under the conditions that the melt viscosity of the thermoplastic resin is adjusted such that the melt flow rate is 500 to 1500 g/10 min, and the twisting angle ¸ of the reinforced fiber bundles with respect to the pultruding direction of the strand is set as follows: 0°<¸<50°. As a result of this configuration, according to the method for producing long-fiber-reinforced thermoplastic resin pellets, pellets in which reinforced fibers are easily untwisted when the pellets are melted so that the reinforced fibers can be uniformly dispersed in molded articles can be produced with high productivity. |
