ない場合も多い。That is, the adhesive strength is preferably 20 kg 725 mm or more using the T-peel method, but since the resin is bonded by heating at 200° C., it cannot withstand high-strength bonding or use in high temperature ranges. In addition, various methods have been proposed for mixing metal powder into resin for the purpose of improving weldability.
It is not very economical because it uses expensive metal powder. Recently, in connection with vibration and noise, soundproofing walls for ships, automobiles, bridges, specifically Shinkansen trains and expressways, as well as OA in offices,
It has a wide variety of applications, such as noise control work for equipment, and depending on the application, conventional laminated steel sheets using resin are often not applicable due to the aforementioned problems with adhesive strength, weldability, and heat resistance.

が望まれていた。Vibration damping materials convert vibration energy into thermal energy and dissipate it, thereby attenuating vibrations and preventing noise. It is widely known that in addition to resin, rubber, and cork, concrete and wood are also effective as damping materials. However, as shown in FIG. 2, the strength and damping performance of a material generally have a contradictory relationship, and it has been desired to develop a material that is good for both.

が高いので高温使用にも耐える。さらに電気伝導性も良
好なので溶接加工という観点からも有利である。Gray cast iron has graphite uniformly dispersed in the Fe matrix, so it has superior damping performance compared to ordinary steel. Furthermore, by sintering cast iron powder to form a porous structure with a predetermined air layer, the damping ability of the negative layer can be improved in addition to the damping ability inherent to cast iron. Moreover, if porous cast iron is used as the intermediate member of the sandwich layer, not only can it be expected to have considerable rigidity, but as shown in the phase diagram in Figure 3, it is also more rigid than materials commonly used for vibration damping materials such as resin. It has a high melting point, so it can withstand high temperature use. Furthermore, since it has good electrical conductivity, it is also advantageous from the viewpoint of welding processing.

途に対してはこの兄囲は限定されるものではない。In detail, as shown in Fig. 1, a cast iron porous layer 1 is placed on a metal base plate 2.
．． The cast iron porous layer 1 preferably has a porous structure with a porosity of 10 to 40%. This is because, as shown in FIG. 4, when the porosity is less than 10, resulting in a dense cast iron layer, the vibration absorption properties are significantly reduced. -When the porosity is 4096 or more, the vibration absorption property improves, but
As shown in FIG. 5, a more porous structure is not preferable because the tensile strength is significantly reduced. Of course, this size is not limited to special uses.

The metal blank 2 is sent out from the coil 3, and a fixed amount of cast iron powder whose particle size is adjusted is cut out from the hopper 4 onto the metal blank 2, and the metal blank 2a fed out from the coil 3a is placed on the cast iron layer 4a. Laminate. A level roller 5 is arranged at the location where the metal blank 2a is laminated onto the cast iron layer 4a to control the thickness of the cast iron layer 4a. Next, the laminated metal plates enter a heating furnace 6, are heated to a predetermined temperature, and are hot-pressed by hot rolling rolls 7. The atmosphere in the heating furnace 6 and the hot rolling roll 7 is desirably non-oxidizing in order to prevent oxidation of the cast iron powder and the surface of the metal plate. The rolled composite steel plate is cut into a predetermined length with a cutter 8, and slowly cooled in a cooling furnace 9 to prevent the cast iron layer from peeling off. Note that by controlling various rolling conditions (rolling temperature, rolling reduction, rolling speed, etc.), it is possible to build the porosity of the cast iron layer 1 to a desired value.

The metal blanks 2, 2a are supplied from coils 3, 3a and heated to a predetermined temperature by a heating heater 10. Cast iron is dripped in a molten state from a pot 11, and an inert gas such as Ar gas or N2 gas is injected from the periphery of the dripping stream from the periphery to gas atomize the cast iron.

The cast iron layer 4a and the metal base plates 2, 2a are pressed together by rolling down the plate to a predetermined thickness using hot rolling rolls 7. The subsequent steps are shown in Figure 6 and the four pillars. The method of layering cast iron on the metal blanks 2, 2a by gas atomization is also possible in the horizontal process shown in FIG. 6 by installing a gas atomization device in place of the hopper 4.

When rolling after heating, the cast iron powder size is 15
0 to +0001 Jm is appropriate from the point of view of damping properties (porosity), and the rolling temperature is 1050 to 1200°C.
The appropriate rolling reduction ratio is 10 to 40%.

ロールするのが望ましく、圧下率としては１０〜４０％
が適当である。As can be seen from the phase diagram shown in FIG. 3, the rolling temperature is preferably just below the melting point of the cast iron layer. This is because if it is rolled in a completely melted state, it will form a dense structure with a porosity of 10% or less, resulting in a significant drop in vibration damping performance. For the same reason, it is desirable to control the rolling reduction rate so that the porosity of the cast iron powder layer is 10 to 40*, and the rolling reduction rate is 10 to 40%.
is appropriate.

ましい。Cast iron powder includes crushed cutting waste from gray cast iron, malleable cast iron, and spheroidal graphite cast iron products, as well as quiche graphite and slag separated from the process of manufacturing foundry pig iron specified in JIS G2202. It is also possible to pulverize coarse-grained iron or directly produce foundry iron by gas atomization or water atomization as shown in FIG. Although there are no particular limitations on the chemical components, it is desirable that C be 3.096 or more, and Si be 1.5!4 or more.
