問題があった。[Problem to be Solved by the Invention 1] In order to make the friction member which is the conventional product mentioned above, it is necessary to perform polishing, and in that case, there are two problems including moss. One of them is, for example, 3. In order to obtain a 5mm+ product, a 5.0mm molded product is required as shown in Figure 2. Approximately 30% of it is discarded during polishing.The other part is heat treated to the inside of the base material. In order to maintain this effect, heat treatment is required for a relatively long period of time. However, even if heat treatment is carried out for a long time, the resin is not oxidized to the inside within one minute, so there is a problem with fading resistance.
これらの問題点に関し研磨せずに製品化するといっそう

きないのが現状である。Regarding these problems, even more disadvantageous problems will arise if the product is manufactured without polishing. That is, although it does not fade, the coefficient of friction (μ) is low overall, the change in μ with respect to the history is large, and the wear is quite severe. Therefore, at present, friction members cannot be manufactured without polishing.

化が進むため酸化促進層１と樹脂リッチ層２ができる。The reason for this deterioration is thought to be as follows. A schematic diagram of the material is shown in Figure 2. First, after thermoforming, the resin tends to collect in the parts that come into contact with the mold, so the surface of the molded product has a high resin content. However, since the outermost surface is oxidized by heat treatment, an oxidation-promoting layer 1 and a resin-rich layer 2 are formed.

ってμの変化が大きくなるという欠点があった。This oxidation-promoting layer 1 has almost no organic components due to thermal decomposition, so it is less likely to fade, but it has low strength and is subject to frequent wear. j, the oxidation promoting layer 1 of the callus is worn out 1
When the resin ridge layer 2 is exposed, this layer should form a resin-rich knot. Since then, there has been a drawback that a difference in μ appears between the oxidation promoting layer 1 and the resin-rich layer 2, and the change in μ increases depending on the history.
本発明は上記欠点を克服するものであり、研磨を不必要

づることを特徴とする。[Means for Solving the Problems] The method for producing a non-abrasive molded friction member of the present invention includes a base fiber with a fiber diameter of 50 μm or less, a resin binder, an organic material such as rubber, and an inorganic filler with a particle diameter of 50 μm or less. including;

造とするためである。In this way, reducing the diameter of the raw materials used and reducing the amount of organic matter between the blends improves the dispersion of the raw materials and makes the molded body porous to allow oxygen to penetrate into the base material, reducing friction after heat treatment. This is to provide a homogeneous structure on both the surface and inside of the member.

J is characterized by sequentially carrying out a molding step of manufacturing a molded body by heating and molding while applying a pressure of 00 kQ/Cm2, and a heat treatment step of heating the obtained molded body. In other words, in this manufacturing method, a well-dispersed grain with a small particle size and particle size is used, and the amount of organic matter blended is small, so even if the molding pressure is increased, the molded product becomes a porous body and oxygen is sufficiently contained in the molded body, and therefore, when this molded body is heat-treated, a friction member is produced in which the difference in the degree of oxidation between the surface and the inside is as small as possible. In addition, in this manufacturing method, the particle size of the raw materials is finely aligned, so the flatness can be improved by significantly increasing the pressing pressure, and the speed (
It is possible to manufacture a friction member that has improved grip and also has increased bonding strength between particles.
