が剥がれてしまうという問題点があった。However, although the metal-ceramic composite material has excellent features, it has a problem that the machining cost is greatly increased due to the difficulty in cutting.
There is also a problem that welding of the metal-ceramic composite material is difficult. In order to solve such a problem, various methods such as brazing and thermal spraying have been attempted to form a laminated structure with an aluminum member that can be welded with good workability, but in all cases, the bonding strength is sufficient. However, when heating and cooling are repeated, there is a problem that the joined portion is peeled off due to a difference in thermal expansion between the members of both layers.

によって達成される。SUMMARY OF THE INVENTION The object of the present invention is to provide a composite material comprising a metal-ceramic composite material containing ceramic powder or ceramic fiber as a reinforcing material and aluminum or an aluminum alloy as a matrix and aluminum or an aluminum alloy. This is achieved by a laminated structural member in which a plurality of layers are laminated, wherein a sheet-like wire mesh is interposed near a boundary layer between the two layers. Another object of the present invention is to pour the molten metal of the lower layer into a mold in which a sheet-like wire mesh is pre-installed near where the boundary layer between the lower layer and the upper layer is formed, and the lower layer is completely solidified. And a step of pouring the molten metal of the member of the upper layer before.

じて適宜決定すれば良い。In the present invention, a mold is used in which a sheet-like wire mesh is previously installed near the boundary layer between the lower layer and the upper layer. The reason is that when pouring the molten metal of the upper layer before the lower layer is completely solidified, the flow of the molten metal may not completely mix the lower layer and the upper layer due to the moderate resistance of the wire mesh. Because it is gone. Therefore, there is an effect that the level of the boundary layer between the two layers is stabilized and the bonding state is improved.
Here, stainless steel or the like is used as the material of the wire mesh, and its wire diameter and aperture may be appropriately determined according to the thickness and size of the laminated structural member.

る。Further, the present invention proposes a method of manufacturing a laminated structural member in which the member of the lower layer is aluminum or an aluminum alloy and the member of the upper layer is a metal-ceramic composite material. The reason for this is that if the two layers are of opposite construction, the effect of replenishing the shrinkage of the member during the solidification and cooling process with a riser will not be sufficiently exhibited, and defects will occur in the metal-ceramic composite material of the lower layer, which is preferable. Because there is no.
