Production system of fiber reinforced composite product

Abstract

The invention discloses a production system of a fiber reinforced composite product. The production system is characterized in that the production system comprises a moving manipulator, a material taking station, a preheating station, an injection molding station and a discharging station, wherein the material taking station, the preheating station, the injection molding station and the discharging station are sequentially arrayed and arranged in the moving direction of the moving manipulator; and a fiberboard material storing area for storing semi-formed fiberboards is arranged on the material taking station, a heating device is arranged on the preheating station, and an on-line mixing injection molding device is arranged on the injection molding station. The production system of the fiber reinforced composite product has the advantages that both injection molding and mold pressing are completed in the on-line mixing injection molding device, the device cost is low, and the productionefficiency is high; the whole system omits the granulation process, so that the cost of raw materials is low; by arranging the heating device, the fiberboards can be preheated first and then are putinto an injection mold for hot pressing performing, so that the fiberboards are bent and formed more easily; and the product with the complex structure can be formed; and meanwhile, the heating devicecan be set, so that the fiberboards are well combined with filled plastic for injection molding, and product performance is improved.

Description

technical field [0001] The invention relates to a production system of composite material products, in particular to a production system of fiber-reinforced composite material products. Background technique [0002] Fiber-reinforced composites are widely used in many fields because of their light weight, good strength and other good material properties. [0003] At present, there are mainly the following methods for the production of fiber-reinforced composite products: hand lay-up molding, winding molding, compression molding and long pellet injection molding. Among them: hand lay-up molding and winding molding processes have long molding cycles, low production efficiency, Labor intensity is high, product quality is difficult to control, etc., and thermosetting resin materials are used, which cannot be recycled. They are mainly used in the production of simple-shaped parts in automobile parts, which are difficult to meet the requirements of industrialized production and env...

[0003] At present, there are mainly the following methods for the production of fiber-reinforced composite products: hand lay-up molding, winding molding, compression molding and long pellet injection molding. Among them: hand lay-up molding and winding molding processes have long molding cycles, low production efficiency, and The labor intensity is high, the product quality is not easy to control, etc., and the thermosetting resin material is used, which cannot be recycled. It is mainly used for the production of simple-shaped parts in automobile parts, which is difficult to meet the requirements of automobile industrial production and environmental protection; Floating fibers will appear on the surface of the product, the precision of the product is low, the product needs to be trimmed and other post-processing, the pressure is low, and only the product with a simple structure can be produced. The produced product has certain limitations, and the semi-finished fiber may need Preforming in advance leads to high equipment investment cost and low efficiency; while in the long pellet injection molding process, the raw materials need to be pelletized first, and the process flow is more, and then after secondary shearing and heating, the fiber length will be shorter, making the product The strength is reduced, and the production cost is also higher
