れがある。 In the above two-layer friction material, the part of the inner heat insulating material layer that is molded into the perforated part of the back metal (molded part) is the part that is not molded into the perforated part (non-molded part) (in contact with the surface of the back metal). Since the density (altitude) is inevitably lower than that of the molded part (referring to the plate part), there is a risk that moisture will penetrate from this mold part, causing rust on the backing metal, and causing the friction material to fall off from the backing metal.

おそれもある。 In addition, when the front friction material layer is a semi-metallic friction material, a backing metal 3 is placed at the interface between the two layers of semi-metallic friction material layer 1 and heat insulating material layer 2, as shown in FIG.
A sparse density area is likely to occur between the molded part 4 and the plate part 5, and there is also a risk that the two-layer materials 1 and 2 will separate at the interface due to rust occurring in this area.

材の脱落を防止するようにしたものである。 The purpose of the present invention is to provide a method for manufacturing a friction material that improves the above-mentioned drawbacks.The purpose of the present invention is to improve friction by making the density of the molded part of the heat insulating material layer equal to or higher than the density of the non-molded part. By keeping the hardness (density) constant in the perforated part (mold part) and plate part of the material and preventing moisture from penetrating from the mold part, rust is prevented and the friction material is prevented from falling off. .
