Description

  The present invention relates to a method for producing an integrally molded part of a metal plate and a carbon fiber reinforced resin sheet, and an integral molded part.

  Conventionally, for the purpose of weight reduction, aluminum-based metals have been used in the skeletons of automobiles and airplanes. When aluminum is used, aluminum is less rigid than a normally used steel plate and needs to be reinforced. For this reason, it may reinforce with a steel plate. However, when aluminum is reinforced with a steel plate, a natural potential difference occurs at the joint surface between the aluminum and the steel plate, and electrochemical corrosion occurs.

  For this reason, in order to prevent this, Patent Document 1 discloses a technique in which a packing made of a material having a low natural potential is interposed.

  FIG. 1 shows an embodiment of the present invention. The integrally molded part of the present invention will be described with reference to FIG.

  FIG. 1 is a perspective view of an integrally molded component 1 according to the first embodiment of the present invention. The integrally molded component 1 is formed by superimposing a metal plate 10 made of a steel plate or an aluminum-based metal and a carbon fiber reinforced resin sheet 20. The end 20T of the carbon fiber reinforced resin sheet 20 is separated from the surface 10S of the metal plate 10 in the integrally molded component 1.

  The carbon fiber reinforced resin sheet 20 is gradually separated from the overlapped portion in a direction away from the metal plate 10. The end 20T of the carbon fiber reinforced resin sheet 20 is separated in a direction away from the metal plate 10 and in a direction perpendicular to the surface 10S of the metal plate 10.

  Therefore, the metal plate 10 does not come into contact with the carbon fiber reinforced resin sheet 20 at the end portion 20T of the carbon fiber reinforced resin sheet 20. In FIG. 2, it is illustrated in an easy-to-understand manner.

  FIG. 2 is a cross-sectional view of the integrally molded component 1 according to the first embodiment of the present invention. The metal plate 10 and the carbon fiber reinforced resin sheet 20 are bonded together, and the end 20T of the carbon fiber reinforced resin sheet 20 is separated from the metal plate 10.

  The carbon fiber reinforced resin sheet 20 is refracted so that the end 20T is separated from the metal plate 10, and is formed away from the surface 10S of the metal plate 10.

  Although not shown on the right side of FIGS. 1 and 2, the end 20T of the carbon fiber reinforced resin sheet 20 is separated from the metal plate 10 as in the left side.

  Thus, since the end 20T of the carbon fiber reinforced resin sheet 20 is separated from the surface of the metal plate 10, even if moisture adheres to the carbon fiber exposed from the end 20T of the carbon fiber reinforced resin sheet 20, There is no difference in natural potential between the metal plate 10 and the metal plate 10 can be prevented from rust.

  Moreover, depending on the place where the integrally molded component 1 is used, the surface of the metal plate 10 may be painted, but when there is no coating, the surface of the carbon fiber reinforced resin sheet 20 is dissolved and adhered to the metal plate 10. Therefore, the present embodiment in which the metal plate 10 is not coated is more effective in bonding.

  Then, the manufacturing method of the integrally molded component which concerns on this embodiment is demonstrated based on FIG. 3 and FIG. FIG. 3 is a flow block diagram showing the integrally molded component manufacturing method according to the first embodiment of the present invention.

The pressing is performed from the carbon fiber reinforced resin sheet 20 side. Alternatively, the lower mold 200 may be heated and the carbon fiber reinforced resin sheet 20 may be heated via the metal plate 10.

  The integrally molded component 1 of the present embodiment is manufactured through the above-described steps. In this embodiment, the separation member is provided on the metal plate side, but the separation member may be provided on the carbon fiber reinforced resin sheet side.
