PROBLEM TO BE SOLVED: To provide a twin screw extruder capable of producing a fiber-reinforced resin molding having the long fiber length of a reinforced fiber and homogeneous characteristics dispersed in a prescribed range by supplying a thermoplastic resin and the roving of the reinforced fiber.SOLUTION: In a twin screw extruder producing a fiber-reinforced resin composition where a molten thermoplastic resin and a roving-like reinforced fiber 31 are sequentially transported to a transportation part, a kneading part and a post-transportation part by a screw in a cylinder 11 and the reinforced fiber 31 is cut, dispersed and kneaded in the thermoplastic resin, a projection member 19 suspending from the inner peripheral surface constriction part 11b of the cylinder 11 of the kneading part is disposed.SELECTED DRAWING: Figure 2 |
