This was realized by applying heat press and joining them in a superposed state. DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings.

  1 to 4 are views showing a first embodiment of the present invention. In the first embodiment, the decoration sheet 1 is basically joined to the surface of the high-rigidity molded products 3 and 5 having a two-layer structure of synthetic resins 3a and 5a and foamed aluminum 3b and 5b. High-rigidity molded products 2 and 4 are formed. FIG. 3 shows a decorative high-rigidity molded product 2 when the resin pressure at the time of molding the high-rigidity molded product 3 is normal, and FIG. 4 shows an increase when the resin pressure at the time of molding the high-rigidity molded product 5 is increased. The decorative high-rigidity molded product 4 is shown.

  As shown in FIG. 1, the decorative sheet 1 has a three-layer structure in which a carbon fiber-containing fabric sheet 1b is sandwiched between two transmission sheets 1a made of a thermoplastic resin. The transmission sheet 1a is made of a thermoplastic resin (for example, polycarbonate) and is translucent such as colorless and transparent, colored and transparent, milky white, and the pattern of the fabric sheet 1b can be seen through the transmission sheet 1a on the surface. Two layers or three or more layers may be used, but the bonding is performed so that the transmission sheet 1a is positioned on the surface side that is always seen in use. A photocatalyst layer (not shown) is formed on the surface of the transmission sheet 1a. Carbon fiber glass and aramid fiber may be mixed in the woven fabric sheet 1b.

  As shown in FIG. 2, the two permeable sheets 1 a and the one woven sheet 1 b are overlapped and hot pressed between a pair of hot press bodies P, so that the transmissive sheet 1 a is softened. Then, the fabric sheet 1b enters the gap between the fibers, and the three layers are integrally joined, and the fabric sheet 1b is embedded in the transmission sheet 1a having a thickness including the two layers.

  Preliminary shaping may be performed on the decorative sheet 1 formed in this way by vacuum forming, pressure forming, hot press forming, or the like in advance according to the shape of the mating part to be joined.

  The foamed aluminum 3b and 5b constituting the high-rigidity molded products 3 and 5 are lightweight and have a specific gravity of 0.3 (variable within a range of 0.2 to 0.8), and have electrostatic shielding properties, conductivity, soundproofing properties, Insulates heat and absorbs shock. For the size of the foamed aluminum 3b, 5b, a 2500 mm × 650 mm × 450 mm object is cut out or sliced as necessary.

  The cell cross section of the foamed aluminum 3b and 5b is exposed at the cross section cut out of the cut or sliced product. The Young's modulus can be increased by press-compressing or roller-pressing the cut or sliced foamed aluminum 3b, 5b. Since the volume is reduced by compression, the specific gravity is increased.

  Then, as shown in FIG. 2, the foamed aluminum 3 b and 5 b are inserted or in-molded into the pair of molding dies M together with the decorative sheet 1. The suction port of the suction passage V is formed on the inner surface forming the cavity space C, and the decorative sheet 1 and the foamed aluminum 3b and 5b are respectively adsorbed to the inner surface. Next, the synthetic resins 3a and 5a are injected into the cavity space C between the decorative sheet 1 and the foamed aluminum 3b and 5b to form the synthetic resins 3a and 5a.

  The molding method may be any of ordinary injection molding, stamping molding, injection press molding, or a combination thereof. Due to the heat of the molten resin, the transparent sheet 1a on the back side of the decorative sheet 1 is softened and reliably joined to the synthetic resins 3a and 5a. The decorative sheet 1 is not a three-layer structure as in this embodiment, but a two-layer structure composed of a simple transmission sheet 1a and a woven sheet 1b, and the heat-softened synthetic resins 3a and 5a are on the back side of the decoration sheet 1. Even when the fabric sheet 1b is in direct contact with the fabric sheet 1b, the molten resin enters the gaps between the fibers of the fabric sheet 1b, so that the fabric sheet 1b is reliably joined.

  Since the foamed aluminum 3b and 5b are inserted or in-molded, the foamed aluminum 3b and 5b take away the heat of the molten resin at the time of molding, and the solidification speed of the synthetic resins 3a and 5a is increased. Occurrence is suppressed.

  The synthetic resins 3a and 5a may be anything as long as they can be used for the molding method (for example, polypropylene). Further, a reinforcing filler for increasing the strength may be mixed in the synthetic resins 3a and 5a.

  Reinforcing fillers include short fiber glass filler (GF), long fiber glass filler (LGF), random long fiber glass filler (RGF / GMT glass mat thermoplastic), glass fiber fabric (TGF), and short fiber carbon. Reinforcing fibers such as fiber (CF), long-fiber carbon fiber (LCF), random long-fiber carbon fiber (RCF), carbon fiber fabric (TCF), stainless steel short fiber (SF), and stainless steel long fiber (LSF) Can be used.

  Even if the resin pressure at the time of molding is normal, the synthetic resin 3a breaks through the cells of the foamed aluminum 3b and partially penetrates into the foamed aluminum 3b (see FIG. 3). Therefore, the joint strength between the synthetic resin 3a and the foamed aluminum 3b is increased by the anchor effect of the synthetic resin 3a with respect to the foamed aluminum 3b.

  When the resin pressure at the time of molding is high, the synthetic resin 5a breaks through the cell of the foamed aluminum 5b and reaches the opposite surface (see FIG. 4). Accordingly, the bonding strength between the synthetic resin 5a and the foamed aluminum 5b is further increased.

  According to the first embodiment, a transparent or translucent transparent sheet 1a made of a thermoplastic resin and a carbon fiber-containing woven sheet 1b are arranged in two or more layers so that the transparent sheet 1a is positioned at least on the surface side. Since the decorative sheet 1 is formed by bonding in the configuration, the decorative sheet 1 is bonded to the surface of the other high-rigidity molded products 3 and 5 so that the transparent sheet is formed on the surface of the high-rigidity molded products 3 and 5. The pattern of the carbon fiber-containing woven fabric sheet 1b that can be seen through from 1a appears, and the decorativeness similar to that of the conventional carbon fiber reinforced resin can be imparted to the high-rigidity molded products 3 and 5. Since the permeable sheet 1a is a thermoplastic resin, the joining with the woven fabric sheet 1b is completed in a short time only by hot pressing, and the decorative sheet 1 can be easily manufactured and is excellent in mass productivity. The thickness of the transmission sheet 1a covering the fabric sheet 1b is also uniform.

The decorative high-rigidity molded product 8 is shown.

  When the resin pressure in FIG. 5 is normal, the synthetic resin 7a breaks through the cells of the foamed aluminum 7b and partially penetrates into the foamed aluminum 7b. When the resin pressure in FIG. 6 is high, the synthetic resin 9a breaks through the cell of the foamed aluminum 9b, the cell destruction portion penetrates, and the two layers of the synthetic resin 9a communicate with each other. Accordingly, the bonding strength between the three layers made of the synthetic resin 9a and the foamed aluminum 9b is further increased.

  In addition, the three-layer structure in which the foamed aluminum 7b and 9b are sandwiched between the synthetic resins 7a and 9a has both sides of the foamed aluminum 7b and 9b covered with the synthetic resins 7a and 9a. There is.
