く、本発明はこのようなエクスパンドメタルの形状特性
を利用して金属多孔質材とするものである。The expanded metal used in the present invention is usually called a lath net or punching metal, as shown in the perspective view in Fig. 3, and is made by making a large number of cuts in a thin metal plate and pulling the cuts in a substantially perpendicular direction to make the whole into a net shape. say something Expanded Metal 1 is not a product made of fine metal wires woven like a metal net, so the cut cross section of the thin metal sheet is twisted by tensile force and deviates not only at right angles to the plane of the thin metal sheet, but also in parallel, diagonal, etc. Because of the twisted portion 4, when the metal fiber layer is pressed onto the twisted portion 4, the metal fiber layer intertwines well with the metal fiber layer, and the present invention utilizes such shape characteristics of the expanded metal to form a metal porous material.

る。The aluminum fiber 2 is a fiber with a diameter of 70 to 250-φ, and has an average tensile strength of about 25 Kg/-1 elongation of 10 to
Since it is 20%, when a laminate is formed with the l-based expanded metal 1 and pressed or rolled, the expanded metal 1 is bitten into the aluminum metal fiber 2 and adheres closely.

Ａｌ系エクスパンドメタル１とが密着する。Aluminum has an elongation of 10 to 20% and has little elastic strain due to plastic deformation, so it can freely undergo plastic deformation without causing elastic deformation due to compression. Furthermore, aluminum-based expanded metal 1 is made by cold rolling an AIl plate,
Partially cut and stretched to make expanded metal. The tensile strength increases to about 50 to 70 Kg/-, and as a result of the compression and shear core force, the AfL metal fiber 2 and the Al-based expanded metal 1 come into close contact.
エクスパンドメタル１は、金属繊維２の両面に張って積
層体としてもよいし、エクスパンドメタル１の片面ある
いは両面に金属繊維２を圧接して積層体としてもよい。The expanded metal 1 may be stretched on both sides of the metal fibers 2 to form a laminate, or the expanded metal 1 may be formed into a laminate by press-contacting the metal fibers 2 to one or both sides.

のため金属が原子間距離近くなるように、圧縮加工を受
けさらに密着強度が強くなる。Furthermore, when rolling the laminate using a press or roll having protrusions on the surface, the laminate partially undergoes further compression, so as shown in the cross-sectional view in Figure 2, the laminate is partially compressed. Expanded metal 3 is formed, and metal fiber 2 is also partially compressed (partial compression method). For this reason, the metal undergoes compression processing so that the distance between atoms becomes closer, further increasing the adhesion strength.
また、この原子間距離に近くなった材料に４００〜５５
０℃の熱を加え、焼成することにより部分的に圧縮され
た箇所はさらに密着性が良好となる。In addition, materials with close to this interatomic distance have 400 to 55
By applying heat at 0° C. and firing, the adhesion of the partially compressed areas becomes even better.
プレスあるいはロール表面の突起は、ロール面に対して
１〜２ａｍの球状あるいは楕円状突起を１０ｏｆに対し
、１〜２ｄの割合で設けることが好ましい。As for the projections on the press or roll surface, it is preferable to provide spherical or elliptical projections of 1 to 2 am on the roll surface at a ratio of 1 to 2 d per 10 of.

Contents of correction (1) Page 6 of the specification, Al series “1 to 20 cm” to r1
Correct to ``more than cm''. (2) Add the following sentence between lines 18 and 19 on page 6. ``Produce metal fibers such as aluminum directly from molten metal.
The aluminum molten metal in the closed container is pressurized with N2 gas or the like, and the pressurized molten metal is spouted out in countless numbers as a molten metal stream from a nozzle to obtain metal fibers such as aluminum having a desired fiber diameter. According to this method, long (1 cm or more) metal fibers with a uniform diameter can be obtained. (3) Add the following sentence between lines 4 and 5 on page 8. "To make metal fibers into a non-woven fabric, metal fibers of the desired length may be piled up in multiple layers and then pressurized and compressed to form a non-woven fabric, but preferably the molten metal is spouted from a nozzle as a stream of molten metal. The metal fibers are received in a direction perpendicular to the direction in which the fibers are ejected, for example, at a position of 1 m to 2 m from the nozzle opening, and after laminating a large number of long metal fibers, they are pressed together to form a nonwoven fabric. 4) Insert the following sentence between lines 15 and 16 on page 8. "At this time, the aluminum fibers 2 near the surface are cut and shortened." (5) Insert the following sentence between lines 18 and 19 on page 10. r The AJZ metal fibers used for the An nonwoven fabric are as follows.
