目からした＼り落ちない。The manufacturing process of the composite material of the present invention as described above is shown in FIGS. 2 to 6, in which a suitable material such as water glass or epoxy is coated on the stainless steel mesh 2 shown in cross section in FIG. A thin layer of adhesive 3 is applied as shown in FIG. In this case, water glass is particularly suitable as the adhesive 3. In other words, the pH value of plate ice glass is around 12, and since it is strongly alkaline, the surface of the intermetallic comrades is extremely sensitive during sintering because it damages not only the short fibers of stainless steel but also the oxide film of the stainless steel mesh. It becomes easier to sinter. In addition, water glass or epoxy adhesives do not drip through the stainless steel mesh due to capillary action.

が一体化焼結された複合材１０が得られる。Next, short fibrous stainless steel 1 having a thickness of 1 to 50 μm and a length of 1 to 1 omm is flocked or sprinkled onto the stainless steel net 2- coated with the adhesive 3. This state is the fourth
As shown in the figure. In this way, fibrous stainless steel 1
is flocked or sprayed onto the stainless steel net 2 and the adhesive 3
After drying, it is rolled between a pair of rolls 4 as shown in FIG. 5, cut into a desired length, and then placed in a sintering furnace as shown in FIG. 6 and first heated at a temperature of about 200 to 400°C to vaporize the adhesive 3, and then heated to the required sintering temperature, e.g.
If the original sintering process is performed by sintering at 000 to 1200°C for a predetermined time, fibrous stainless steel 1 and stainless steel mesh 2 will be formed.
A composite material 10 is obtained which is integrally sintered.

化されていて焼結が一層容易となる。In the sintered composite of the fibrous stainless steel and stainless steel mesh of the present invention, the short fibrous stainless steel has been subjected to considerable cold working during the rolling process, resulting in areas where dislocations are concentrated. In particular, since the intersection portions of the fibers have been subjected to severe cold working, the intersection portions are activated by dislocations, making sintering easier.

Roll rolling was carried out at a pressure of about 100%. This was further placed in a furnace at about 400'C to evaporate moisture for 5 minutes in order to evaporate the water glass adhesive. Therefore, there is no dislocation of the stainless steel rut fibers and no change in the nickel carbonyl powder during combustion in this short period of time. Next, it was necessary to completely integrate the above materials by sintering, so this was sintered for 1 hour in a furnace at a temperature of 1180°C and a dew point of -40t for 30 minutes, resulting in a porosity of 80%, Thickness 0
