板が車体や航空機用構造部材等に広く使用されている。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a method for manufacturing a molded composite plate in which a porous metal having a membrane structure is used as a core material and a plate material such as a metal plate is used as a reinforcing material. 1゜(Prior art) Conventionally, many composite boards have been used for building materials and structural components, and especially for light products, sandwich composite boards with a honeycomb structured light metal core reinforced with metal plates are used as high-strength composite boards. Boards are widely used for car bodies, aircraft structural members, etc.

加工することは困難である、。When this composite plate is used as a building material or a structural member, it is not limited to a flat plate, but is applied in various shapes, so it is necessary to mold it into various shapes. However, these composite plates are generally thick, and composite plates with reinforcing materials pre-adhered to both the front and back sides are restrained by the reinforcing materials on the tension side and compression side due to bending, so it is difficult to form composite plates. be,.

ある。(Purpose of the Invention) This invention was made in order to eliminate such conventional drawbacks, and it provides a lightweight and high-quality product that uses a porous metal made of membrane filament as a core material and the material in front of the metal plate as a reinforcing material. 1゜ (Structure of the Invention) This invention provides a method for easily forming a strong composite plate. The reinforcing plate is formed in a thin state, and then the core material and the reinforcing plate are bonded.

両者を確実に接着することがＣきる。In the ten structure, the core material and the reinforcement are not bonded to each other during molding! In addition, it deforms without being constrained by the phase U, and therefore can be easily formed and processed.
Moreover, in order to process the two parts together,
After processing, the two can be reliably bonded at room temperature or by heating.

これによって補強板２を芯材１の両面に接着させる。(Example) In FIG. 1, adhesive layers 3 are superimposed on both sides of a porous metal flat core material 1 having a membrane structure, and a reinforcing plate 2 is superimposed on the outer side of the rough surface. These are simply placed on top of each other and are not glued together. This laminate 40 is placed on the concave mold 8b, and the convex mold 8 is placed on the concave mold 8b from above.
By pressing with a, the laminate 4 is formed into a predetermined shape as shown in FIG. Then, by heating this laminated layer with an appropriate heating means, the adhesive layer 3 is melted,
As a result, the reinforcing plate 2 is bonded to both sides of the core material 1.

なるように設定するのが好ましい。To produce a porous metal plate having the above-mentioned membrane structure, for example, a foaming material of calcium metal and a thickening material of titanium hydride are added to molten metal such as fluminiram, and cast using a known casting method C. , a large number of closed cells are formed, and these 'Q foams are allowed to rest in a bright place to a predetermined plate thickness. The degree of foaming is as follows: apparent specific gravity is 0.27, bubble size is 2, 1011111
1. It is preferable to set the shell layer to have a structure having a thickness of 10 to 200 μ and no h-tropism.

ウム板等の金属板を用いればよい。As the adhesive, a thermosetting sheet of own equipment is used, or a liquid adhesive such as 1-bore 4° resin or rubber adhesive is used, and the reinforcing plate is an aluminum plate, etc. It is sufficient to use a metal plate.

易になされる。。In the above molding process, since the core material 1, the adhesive layer 3, the reinforcing plate 2, and C and LU are not bonded to each other, when subjected to bending h, the contact surfaces of each other are squeezed, and the In this case, each member having low rigidity is deformed, and therefore, the molding is easily done in the auditorium. In other words, if bending force is applied after each member is bonded, the reinforcing materials on both sides exhibit resistance to bending, making it difficult to form, and the core material is destroyed and the composite plate is compressively deformed at the bending part. (thickness decreases) or the bonded portion peels off, but if bending force is applied to each member, deformation can be easily achieved. .

を行うことがＣきる。The mechanical properties of aluminum foam are shown in Figure 4 (A) (F3
) (C), and when bending is performed, the tension side can withstand up to the yield point, so the bending is performed at point 11 just below the yield point, and the compression side is When the yield point is exceeded, the shell layer buckles, but the buckling progresses while the compressive strength fluctuates, so bending is performed at point 12r in the middle, and the bending properties are large against the bending load. Flexibility will be exhibited, and therefore the shell layer will be increased at point 13 just before it is destroyed.
All you have to do is do this. If molding is performed under such conditions, cold molding can be performed without destroying the core material.

定の形状に成形する。FIG. 3 shows a method for continuously carrying out one culm, in which the 18-long core material 1 is transported by a single transport stage (not shown), and a layer 3 of adhesive material is applied to the core material 1 from a supply means 30 disposed in the middle. The reinforcing plates 2 are laminated on both sides of the core material 1 via the connecting links 3 by supplying the reinforcing plates 2 onto both sides of the core material 1 from the supplying means 20. The laminate is then sandwiched between a concave mold 9b and a convex mold 9a to form a predetermined shape.

The formed part is sent into a heating furnace 9, where it is heated so that the adhesive layer 3 melts and the core material 1 is heated.
The reinforcing plate 2 is adhered to the molded laminate 22 to form a molded laminate 22.

。In addition, in the above example, an example was shown in which the adhesive layer and the reinforcing plate were superimposed on both of the core materials. With the reinforcing plates stacked one on top of the other, heat bond the molded part for 1'i, then bond the reinforcing plate to the other side for 6 minutes.
In this case as well, the forming part [ can be similarly easily performed.
