Abstract

PURPOSE:To realize the cost reduction of composite material by a method wherein integral forming is performed by forming fiber reinforced plastic hollow tube and simultaneously forcing resin concrete in the hollow part and finally hardening the concrete. CONSTITUTION:Resin impregnated roving 2, which is passed through a resin impregnating tank and, after that, shaped with a shaping guide into the form conforming to a die, is fed to a hot die 3. A resin concrete pouring nozzle 1, the shape of which corresponds to the forming shape, is inserted in the central part on the inlet side of the hot mold 3 so as to mold an outer shell 4 out of fiber reinforced resin. At the same time, resin concrete 5 is forced in the interior of a molded item so as to be filled in order to be thermoset together with the outer shell, resulting in continuously producing fiber reinforced plastic- resin concrete composite material. Thus, low cost and high strength fiber reinforced plastic-resin concrete composite material can be easily and continuously manufactured by pultrusion.

る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a method for producing a fiber-reinforced plastic-resin concrete composite material, which is a composite of a drawn fiber-reinforced plastic material and resin concrete (hereinafter referred to as "resin concrete"). Regarding. More specifically, the present invention relates to a method for producing a fiber-reinforced plastic-resin composite material, in which a certain type of fiber-reinforced plastic and a plastic mold are simultaneously formed in a drawing system.

る。The pultrusion method is one of the conventionally widely known continuous forming methods for reinforced plastics. It is characterized in that a long material such as long fibers is used as a reinforcing material, and a long molded product can be obtained continuously. The application of shaped products obtained by this pultrusion method to structural materials, housing-related materials, etc. is expanding.

はまだ開発されていなかった。However, in order to obtain the strength required for these structural materials, etc., the conventional pultrusion method requires thickening of the material, and the material is made of long fibers and organic materials such as cured unsaturated polyester. Since it is mainly composed of a matrix, a large amount of reinforcing materials such as long fibers are used, but for general use there are problems such as excessive quality and high cost of the product. Therefore, in order to meet this demand, a method of manufacturing a composite material in which the outer shell is made of fiber-reinforced plastic and the inside is filled with resin, etc. has been studied. A manufacturing method that satisfies the current demands for low cost and high productivity has not yet been developed.

レジコン複合材を連続的に形成せしめる。That is, the method for producing a fiber-reinforced plastic-resin concrete composite material of the present invention involves a pultrusion method in which resin impregnation and hot molding are continuously carried out while continuously supplying long fibers as a reinforcing material. This method is characterized by integrally molding a hollow cylinder of fiber-reinforced plastic by simultaneously press-fitting and hardening a resin into the hollow part. In other words, the pultruded article obtained by the method of the present invention is a composite material having a structure in which resin is filled and hardened inside an outer shell made of fiber-reinforced plastic. Hereinafter, the present invention will be explained in more detail.The resin-impregnated roving, which has been passed through a resin-impregnated tank and shaped according to the mold by a shaping guide, is drawn into a hot mold 3 as shown in FIG. In the mold 3, a resin injection nozzle shaped according to the shape of the precept is inserted into the center part on the entrance side, and the resin is press-fitted and filled into the inside of the molded product using a pump while molding an outer shell made of fiber reinforced resin. The fiber-reinforced plastic is then heat-cured together with the outer shell.
A resin composite material is formed continuously.
