Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a preformed carbon molded article, and more particularly, to a method of manufacturing a preformed carbon molded article by which a carbon molded article using carbon as a main raw material is molded and then the two carbon molded articles are more firmly bonded.
As the molding technology develops, devices or machines using various kinds of molded products are used.
Particularly, in the case of a vehicle body or an outer shape constituting a vehicle, studies have been actively made on a body having a high strength and light weight in order to save fuel, and Patent Literature 1 is known as a technology related to such a high- .
Patent Document 1 includes an underbody portion provided in the form of a single horizontal plate extending from the front to the rear of the vehicle and a raised portion integrally formed on the outer periphery of the underbody portion and having an "A" The impact energy absorbing plate assembled with the adhesive or the bolt and the nut is assembled to the ridge portion while the lower portion of the ridge portion is finished, and the lower portion is closed by the impact energy absorbing plate The inside of each ridge is a technique related to a vehicle body using carbon fibers having either a collision energy absorbing agent or a tube, or a collision energy absorbing material together with a tube so as to enhance the impact energy absorbing capability.
Carbon and reinforced plastic are widely used as materials for producing high-strength and lightweight structures, and structures made of carbon and reinforced plastic are formed by joining two or more pieces of carbon molded pieces together to form a single molded product. In the method of connecting the carbon molded product pieces to each other, a method is used in which the same reinforcing plastic material as the material of the molded product is supplied to the two bonding surfaces and hardened.
That is, as shown in FIG. 4, the molten reinforced plastic bonding material is applied to the joint portions of the two carbon molded product pieces, and the joint portions are pressed so as to be joined to each other, and then the joint resin is cured to join the joint portions.
However, once hardened plastic has surface tension on its surface and even if a reinforced plastic adhesive resin of the same material is used on such a surface, if the impact surface is not firmly adhered to the adhesive surface, There is a problem.
SUMMARY OF THE INVENTION The present invention has been developed in order to solve the above problems, and it is an object of the present invention to provide a method of manufacturing a prefabricated carbon molded article, in which two carbon moldings can be more firmly bonded after a carbon mold- do.
More particularly, the present invention relates to a method for producing a single molded product by joining a plurality of pieces of carbon molded product made of carbon fiber and reinforced plastic to form a molded product. In the molding process, the carbon fiber is exposed to the joint, So that the joining portions are more firmly joined to each other.
A method for manufacturing a prefabricated carbon molded article for achieving the above object is a method for manufacturing a carbon molded article, which is produced by joining two or more pieces of carbon molded articles made by dividing one another, the method comprising the steps of impregnating a carp base with resin, A molding step of molding at least one piece of carbon molded product; A piece joining step of joining the formed carbon molded piece pieces together to form a single molded product; And a finishing step of finishing the assembled moldings,
The molding step may be performed such that the carbon yarn of the joining portion to which the carbon molded piece is bonded to each other is exposed. In the carving joining step, the carbon yarn exposed at the joining portion of the carbon molded piece formed in the molding step is overlapped with each other, And the bonding resin is applied between the carbon yarns.
Preferably, the joining portions of the carbon molded piece are overlapped with each other, and the fixing grooves and the fixing protrusions may be formed on the mutually facing surfaces.
As described above, in the method of manufacturing the prefabricated carbon molded product according to the present invention, the carbon yarn is exposed to the joining portion in the forming process, and the joining resin is supplied between the two joining faces in a state in which the exposed carbon yarns are overlapped with each other, The joined portion of the carbon molded article can be more firmly bonded.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
Like reference numerals are used for like elements in describing each drawing. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method of manufacturing a prefabricated carbon molding according to the present invention will be described in detail with reference to the accompanying drawings.
As shown in Fig. 1, the molded product made by the present invention may be a car body or a water tank, though not shown, and the molded product is made into a plurality of pieces so that the mold can be easily separated during the demolding process of the mold .
Particularly, in the case of a large-sized molded article as shown in FIG. 1, a plurality of carbon molded pieces are molded so as to facilitate handling, and then these carbon molded pieces are assembled and joined to each other to form a single molded article.
That is, the manufacturing process of the carbon molded product mainly includes a molding step of molding two or more pieces of carbon molded piece that are separated from each other by impregnating resin into a car base, and a joining step of joining the molded carbon molded pieces together to form a single molded product .
Needless to say, the step of finishing the finished molded article to have a beautiful appearance by finishing the surface of the finished assembly is further performed.
Such a conventional method for molding a carbon molding is conventional, and a feature of the present invention is a technique of bonding a plurality of pieces of carbon molded piece to each other.
Of course, in order to bond the two carbon molded pieces with each other using the joining method of the present invention, the
