The thermosetting resin film used in the present invention contains a powdery, flake-like and / or short fibrous substance containing a metallic component, and the substance containing the metallic component is a powder. There is no particular limitation as long as it contains a metallic component on the whole or surface and / or inside of the body-like, flake-like or short fibrous substance, and the metallic component is, for example, silver, nickel,

By selecting a conductive resin film, it is possible to easily and inexpensively provide a metal plating coating layer having excellent adhesion. The thermosetting resin film needs to contain the substance containing the above metallic component (hereinafter, may be abbreviated as metallic substance) in a proportion of 10 to 40% by volume. If this amount is less than 10% by volume, it is difficult to make the surface of the obtained product metallic so as to give conductivity, and particularly to a metallic surface that can be plated. On the other hand, if the content exceeds 40% by volume, the function as a film is usually impaired, depending on the density and form of the metallic substance used, and the strength and tackiness of the film itself at the time of attachment are poor, making attachment work difficult.

These thermosetting resins are usually used together with a curing agent and, if necessary, a curing accelerator / catalyst, etc., and the curing agent and the curing accelerator / catalyst are appropriately selected according to the type of the thermosetting resin used. . Further, when the resin of the molded product main body and the resin of the thermosetting resin film used for the outer layer are different, the problem of peeling at the interface and distortion at the time of molding may occur. It is advantageous to use Further, in the case of an epoxy resin system, it is desirable to use a resin or a curing agent having the same curing characteristics. For example, when manufacturing a pipe-shaped carbon fiber reinforced resin molded product, since prepreg using an epoxy resin is widely marketed, in the same resin system as the above prepreg, or in a range that can be handled as a film, Adjust the compounding ratio of the resin system of the prepreg,
Resin system with low viscosity
A thermosetting resin film containing 0% by volume can be produced, and both can be easily produced by a rolling molding method or a tape winding method. Further, as long as the function as a film is not impaired, an antioxidant, a dispersant, a plasticizer,
Additives such as colorants can also be added.

A porous sheet material is used mainly for the purpose of extracting only a resin component from a thermosetting resin film containing 40% by volume. The resin component contained in the thermosetting resin film, once in the middle of the heat and pressure curing process, the viscosity is once reduced, resulting in a state of rich fluidity, therefore, the thermosetting resin film in the outer layer, further If the outer sheet is thermocompression-bonded with the porous sheet-like material attached, the dense metallic material does not flow, and only the resin component rich in fluidity is absorbed by the porous sheet-like material, The content of the metallic substance is increased at least 1.2 times. That is, by adopting the method of the present invention, a resin molded product having a more metallic surface layer, which cannot be achieved only by pasting a thermosetting resin film containing a metallic substance and thermally curing it, is produced. It becomes possible to do.

A material having a sucking function can be used, and a glass fiber woven fabric, newspaper, etc. are particularly preferable. Further, by using a release-treated glass fabric or the like, the porous sheet layer cured in the sucked state can be easily removed by hand. The content of the metallic substance in the surface layer of the resin molded product is calculated from the resin absorption amount, but depending on the type of metal, it can be determined by the acid decomposition method or the combustion method. Further, if the metallic substance is spherical, it is possible to simply perform a binarization process on the polished surface microscopic image of the surface layer and roughly estimate it as an area ratio.

はいうまでもない。First, a carbon fiber prepreg is laminated on a core metal according to a design to a predetermined thickness, and then one or more thermosetting resin films containing 10 to 40% by volume of the metallic substance are attached thereon. At this time, the thickness of the film to be attached and the number of laminated layers can be freely changed according to the design, and are not restricted. Next, one or more porous sheet-like materials for removing the resin from the film are attached onto the thermosetting resin film.
The amount of resin removed from the resin film is controlled by the suction performance of the porous sheet material, the amount of attachment, the heat and pressure conditions during curing and molding, and depending on the conditions, the prepreg of the lower layer, etc. It goes without saying that it is necessary to set the conditions.

ることができる。In this example, finally, the heat shrink tape is wound under predetermined conditions, and then the core metal is heat-cured under predetermined conditions. At this stage of heat curing, a predetermined amount of the resin is extracted by taking advantage of the winding tension of the heat shrink tape, the heat shrink force and the viscosity reduction due to the heating of the resin component, and the amount of the metallic substance in the surface layer is at least 1.2 times. Raise to. In the present invention, the object is to convert the surface of the product into a metallic substance, and when the amount of the metallic substance in the surface layer is less than 1.2 times, the surface of the molded article is substantially the degree of contact between the metallic substances. Is not improved, and the surface has no conductivity, or the surface is rich in resin and not metal. In autoclave molding, the amount of resin withdrawn can be adjusted by appropriately setting the degree of vacuum and the pressure applied during molding instead of using the heat-shrinkable tape.

ところ、約0.５Ω／１０ｃｍであった。As the nickel powder-containing resin film, a film containing 30% by volume of nickel powder (manufactured by Taiheiyo Metal Co., Ltd., particle size: 325 mesh or less) and having a thickness of 250 μm at 70 ° C. was used. Further, four layers of release-treated glass fiber cloth (Bleeder Release B, manufactured by Airtech Co., Ltd.) were wound around it, and a heat-shrinkable tape having a width of 15 mm was wound around it with a tension of 3 kg, and then at 120 ° C. for 2 hours. It was cured while rotating over time. After cooling to room temperature, the heat shrink tape and the glass fiber cloth were removed to produce a surface nickel pipe. At this time, only the resin had permeated all the four layers of the glass fiber cloth. The cross section of the obtained pipe was observed by a scanning electron microscope (SEM), and the thickness of the nickel powder-containing surface layer was measured and found to be approximately 500 μm. That is, the content of nickel powder in the surface layer was calculated to be 45 vol%, and the surface of the pipe was binarized by polishing the pipe surface with # 800 sandpaper and observing with a polarizing microscope at a magnification of 200. When the ratio was calculated, a value of 48% was obtained. On the other hand, when the electric resistance between two points on this surface was measured with a tester, it was about 0.5 Ω / 10 cm.

When the cross section of this pipe was observed by SEM, the thickness of the nickel powder-containing layer was not uniform and the electric resistance was infinite. Furthermore, since the surface has poor conductivity, electro nickel plating could not be performed even under low current conditions.
