The utility model discloses a twin-screw extruder for composite materials, comprising a base. An extruder shell is arranged on the base, a feeding port is formed in the upper end surface of the extruder shell, a feeding mechanism is arranged on the feeding port, an extrusion mechanism is arranged in the extruder shell, a melting chamber is arranged at one end of the extrusion mechanism, and a discharge port is arranged at one end of the extrusion mechanism away from the melting chamber in the extruder shell. By arranging a sealing cover at the top of the feeding hopper, a closed feeding space is formed between the sealing cover and the feeding hopper. Composite raw materials are input into the feeding space through a feeding pipe, and dust generated by the impact of composite raw materials on the inner wall of the feeding hopper is blocked by the sealing cover without dust flying. Then, the composite raw materials are mixed evenly under the action of stirring blades and enter the feeding port through a connecting pipe for processing, so that the composite raw materials are retained to the greatest extent, the waste of raw materials is reduced, and the pollution to the production environment and the risk of dust explosion are reduced.
