The invention relates to a method for pultrusion of a mixture with plastic, continuous fibers and reinforcing fibers. The method is characterized in that a first extruder, a second extruder, a die anda conveying device are included, wherein the first extruder comprises a first inlet, a second inlet and a first outlet; the second extruder comprises a third inlet, a fourth inlet and a second outlet; the die comprises a plastic inlet, a continuous fiber inlet, a reinforcing fiber inlet and a product outlet; the first extruder is arranged close to the plastic inlet; the second extruder is arranged close to the reinforcing fiber inlet; and the conveying device is positioned below the die and used for conveying the die. According to the method, the defect that a single extruder cannot be corrected in the later period is overcome, and the formed product is high in compactness, good in strength and good in performance.
Description
technical field [0001] The invention relates to the technical field of molding methods, in particular to a pultrusion molding method mixed with plastics, continuous fibers and reinforcing fibers. Background technique [0002] At present, the pultrusion molding process is mainly used for thermosetting plastics, and the pultrusion molding of reinforced thermoplastics is not involved much in the production. In the prior art, the pultrusion molding process usually uses an extruder to perform pultrusion to obtain the corresponding Profiles, the added raw materials are limited, and lack of post-correction, resulting in poor compactness of the obtained product, and thus poor product performance and poor strength. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies and defects in the prior art, the present invention provides a pultrusion molding method mixed with plastics, continuous fibers and re...
