Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for molding a fiber-reinforced plastic composite material and electrodepositing it onto the molded product, and more specifically, it relates to a method of forming a fiber-reinforced plastic composite material and electrodepositing it onto the molded product, and more particularly, it relates to a method of forming a thermosetting material of a desired thickness onto a mandrel of a desired shape. This paper proposes a method for molding a fiber-reinforced plastic composite material coated with a resin to make it easier to obtain a plated film with good adhesion, and a method for plating the molded product.

Conventional molding methods and electrodeposition methods involve creating a molded product made of carbon-based, boron-based or silica-based fiber-reinforced plastic in the desired shape, and then applying vapor deposition, thermal spraying, conductive coating, or electroplating. etc. With these methods, it is difficult to obtain a conductive film with good adhesion, and moreover, it is technically impossible to obtain a molded product with a complicated shape. The purpose of this invention is to improve the adhesion of the plating film, and by providing a thermosetting resin layer with a required thickness on the surface layer during molding of a fiber-reinforced plastic composite material and increasing the contact area with the plating layer. This aims to improve the adhesion (2 to 9/C7TL) with the plating film.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1a shows a cylindrical waveguide manufactured according to the present invention, in which 1 is a cylindrical core, and 2 is a fiber-reinforced type obtained by melting or removing the core 1. It is a waveguide reinforced with plastic composite material. Figure 1b is Figure 1a(1)A
- It is a diagram showing a cross section of the A' plane, and the electroless gold plating 7 is applied to the inner surface of the waveguide 2 to prevent discoloration of the electroless silver plating 6, so that it is thin enough not to impair the conductivity of the silver. In order to obtain good conductivity of the waveguide, electroless silver plating 6 and electroless copper plating 5 are applied.

FIG. 2 is a diagram showing the manufacturing process. By applying the thermosetting resin 4 to the required thickness before laminating and curing the fiber-reinforced composite material 3 on the mandrel 1, it is possible to achieve /
(While I could only obtain the adhesion strength of the plated film of V7!, I have made it possible to obtain the adhesion strength of 2/9/my plated film.

The fiber-reinforced composite material 3 is then laminated and cured to increase the strength of the waveguide and to reduce its weight. Examples of the present invention are as follows.

〔Example〕

As described above, according to the present invention, any shape can be plated simply by dipping it, so no particularly difficult techniques are required.
