BEST MODE FOR CARRYING OUT THE INVENTION A reinforcing panel material according to the present invention and a light-shielding panel for an automobile using the same do not require an inner panel and an outer panel as in the prior art, and use a metal wire as a member corresponding to the outer panel. Since it is configured by sticking to the inner panel surface, the configuration is extremely simple, so that the weight can be reduced, the press molding can be simplified, and the manufacturing process can be simplified.

The present invention will be described below with reference to the drawings showing embodiments of the present invention. First, FIG. 4 is a schematic perspective view illustrating a case where the reinforcing panel of the present invention is formed as a light shielding panel for an automobile. In FIG. 4, reference numeral 10 denotes a thin inner panel. This inner panel 10 is, for example, 0.
A3003-H2 for 3 to 0.4mm thick aluminum alloy
Use about 0.5mm thick 4 plates. The panel shown in FIG. 4 is formed to have a two-dimensional curved surface or a three-dimensional curved surface that is substantially the same as the automobile ceiling. On the two-dimensional or three-dimensional bending convex surface of the inner panel 10, a metal wire 11 is attached. The metal wire 11 is attached so that it can be reinforced over the entire convex surface of the inner panel 10, and especially the knob hole which is easily subjected to large external force
It is stuck tightly to 12 and the rail. Wire 11
May be any wire as long as it is a metal wire having strength and rigidity.For example, when using a steel wire, a piano wire or the like having a diameter of about 0.5 to 2.0 mm, and when using an aluminum wire, High intensity lines such as A2024BD and A2024W are preferred. Needless to say, other known high-strength wires can be used. After bending, these metal wires 11 are preferably subjected to aging and center distribution. Further, metal wires may be attached to both sides of the reinforcing panel. Further, two or more metal wires may be used and attached.

[0007] The thin inner panel 10 is subjected to various bending processes in accordance with the mode of use. When the reinforcing panel material is used as an automobile light-shielding panel, it is bent into a shape having a two-dimensional or three-dimensional curved surface that is substantially the same as the automobile ceiling. These bending processes may be performed by normal pressing, but by performing bending using a twin roll consisting of a metal roll and a resin roll, an inner panel having an extremely large polar ratio (for example, R5000 to R10000) can be obtained without springback. Can be The two-dimensional or three-dimensional bending may be performed before attaching the metal wire 11 on the surface of the inner panel 10, or may be performed on the inner panel 10 after attaching the metal wire 11.

[0008] Metal wire on the surface of the inner panel 10
A known adhesive can be used to attach 11. The application is performed by applying an adhesive on the surface of the inner panel 10 or pasting an adhesive application tape on the surface of the inner panel 10 and pressing the wire 11 thereon. Preferably, an adhesive is applied to and coated on the metal wire 11 in advance, and this is bonded to the surface of the inner panel 10 by a heat press. Metal wire 11 on the inner panel 10 surface with the metal wire 11 attached
A cloth may be stuck on top. This cloth sticking is not only on the inner panel 10 surface including 11 parts of metal wire,
It may be attached over the entire surface of the inner panel 10. In addition, it is preferable that the cloth is attached to the back side of the inner panel 10, for example, in the case of a light shielding panel for an automobile, to be attached to the entire inner surface of the vehicle. The metal wire 11
May be performed simultaneously with the cloth.

FIG. 4 shows an example in which the reinforcing panel material according to the present invention is applied as a light-shielding panel for an automobile. The reinforcing panel material according to the present invention can be widely used for the above-mentioned various applications. In accordance with the above, the inner panel is formed into a two-dimensional or three-dimensional shape in accordance with the shape of the inner panel, and metal wires are attached at appropriate intervals or in a number to a portion where the strength or rigidity is required.

[0010]

According to the present invention as described above, the strength and rigidity are superior to the conventional resin-reinforced panel material, and the weight is reduced as compared with the conventional panel material using the inner panel and the outer panel. Can be achieved, the manufacturing method is extremely simple, and the manufacturing cost can be kept low. In addition, since the strength and rigidity depend on the strength and arrangement of the metal wires, it is possible to easily cope with a portion where strength and rigidity are required by appropriately disposing the metal wires relatively densely. .
