The planar shape of the desired friction material product is cut out from the sheet, and the cut friction material sheets (a) of the same shape are laminated to the thickness of the desired friction material product as shown in the figure, and fired to obtain the desired friction material. We are getting wood products.

), the temperature experienced by the material is that the sheet on the friction surface side (a') is high, but the sheet on the inside side (alJ) is high.
has a lower temperature than sheet (a'). However, since the strength of the interface (b) between the two sheets (a') and (a'') is weak, there is a drawback that delamination occurs due to thermal stress caused by the difference between the surface temperature and the internal temperature.To overcome this drawback, 2 above
A method of three-dimensional knitting instead of a dimensional knitting sheet is also considered, but this is extremely disadvantageous due to high cost.

A large number of friction material sheets mainly composed of M and matrix resin are laminated and formed into a block body whose cross section perpendicular to the surface of the friction material sheet forms the planar shape of the friction material product.After firing, this is shaped into a desired shape. The intended purpose is achieved by cutting to a thickness to obtain a friction material product having the above-mentioned cross-sectional shape.
即ち本発明では前出の２次元編みシートをそのまま多数

所期の製品を得るものである。That is, in the present invention, a large number of the aforementioned two-dimensional knitted sheets are laminated as they are, formed into a predetermined block body, and after firing, each two-dimensional knitted sheet is laminated.
The desired product is obtained by sequentially cutting out cross sections perpendicular to the dimensionally knitted sheet.
従って第２図の従来法では摩擦材製品は１個１個の生産

しく向上せしめることができる。Therefore, in the conventional method shown in Figure 2, friction material products are produced one by one, whereas in the method of the present invention, many products can be produced simultaneously because they are cut out from a block, which significantly improves productivity. You can force it.

離は生じない。Further, in the friction material product produced by the method of the present invention, a similar laminated structure appears on the friction surface and the internal surface, and both are reinforced with fibers, so that when used, 11! Even if a temperature difference occurs between the rubbing surface and the inner surface, there is little thermal stress between them, and therefore no delamination occurs between the two surfaces as in conventional products.
