By the way, the counterpart material of the friction material is usually a metal such as iron. Then, due to friction sliding with the friction material, the mating material wears and wear powder such as iron powder is generated. However, in a friction material containing metal fibers or metal powder, a phenomenon (metal catch) that wear particles are easily transferred to the surface of the metal fibers or metal powder is observed, probably because the metals are the same. When the abrasion powder is transferred to the surface of the metal fiber or the metal powder in this manner, there is a problem that the surface of the mating material is more likely to be scraped by the abrasion powder during idling.

[0006] For example, when the brake pad contains metal fibers or metal powder such as steel or copper, the wear powder (iron) of the rotor of the mating material is easily transferred to the surface of the metal fiber or metal powder, and the wear powder causes the wear powder. The rotor is further partially scraped, and a difference in wall thickness of the rotor grows. When the thickness difference of the rotor becomes large, there is a problem that brake vibration is generated during braking and an occupant feels uncomfortable.

When the lubricant is mixed as in the above publication, the wear of the mating material due to the metal fibers or the metal powder is reduced to some extent, but the transfer of the wear powder to the surface of the metal fiber or the metal powder is prevented. It was difficult and it was inevitable that similar problems such as brake vibration would occur. The present invention has been made in view of such circumstances, even when using a metal fiber or metal powder, to prevent the transfer of wear powder of the mating material to the metal fiber or metal powder, The objective is to reduce the aggressiveness of the opponent material.

In the friction material of the present invention, the metal fiber or the metal powder is covered with the resin layer having the solid lubricant powder held on at least the surface thereof. Therefore, during frictional sliding between the friction material of the present invention and the mating material, a lubricating film of the solid lubricant is formed between the metal fiber or metal powder and the mating material, so that the mating material causes wear of the mating material. At the same time, the abrasion powder of the mating material is prevented from being transferred to the metal fiber or the surface of the metal powder. As a result, wear of the mating member is further prevented, and brake vibration is prevented from occurring.

The material of the substrate is not particularly limited as long as it is made of metal, and various metals or various alloys such as copper, iron, brass, nickel and aluminum can be selected and used. This substrate can be included in the fiber substrate if it is a metal fiber. Further, metal powder can be included in the filler and the friction modifier. As a material for the resin layer, a resin having excellent heat resistance is desirable, and a phenol resin,
Examples thereof include thermosetting resins such as epoxy resins and thermoplastic resins such as polyamide-imide. The thickness of this resin layer is not particularly limited, but it is preferably as thin as possible within the range where the solid lubricant powder can be held. If it is too thin, the solid lubricant powder peels off and the durability of the effect decreases. On the other hand, if it is too thick, the strength of the resin layer will decrease, and the resin layer will fall off during frictional sliding, and the durability of the effect will also decrease. A range of 1 to 10 μm is suitable.

As a material for the resin layer, one that is soluble in a solvent such as an organic solvent is particularly desirable. By dissolving it in a solvent to form a solution, the coating process on the substrate can be performed easily, and the solid lubricant powder can be easily attached due to the adhesiveness of the solution, and the solid lubricant powder can also be solidified. This is because the lubricant powder can be easily held in the resin layer while ensuring the adhesive strength.

As the solid lubricant powder, graphite,
Examples of the powder include molybdenum disulfide, carbon black, and antimony trisulfide. The particle size of this powder is not particularly limited, but is preferably in the range of 1 to 20 μm. If it is smaller than 1 μm, it may be difficult to handle, and if it is larger than 20 μm, the retention property in the resin layer may be poor. The amount of the solid lubricant powder retained in the resin layer is effective even if it is small, but an amount enough to cover the surface of the resin layer is optimal. If the amount is too large, the holding power is lowered and the effect is less durable.

In order to produce such metal fibers or metal powder, it is desirable to first apply a solution in which a resin is dissolved in a solvent to a metal substrate to form a resin layer. According to this method, the film thickness of the resin layer can be easily controlled only by adjusting the resin concentration in the solution. Then, by adhering the solid lubricant powder before the solvent of the resin layer is volatilized and then drying it, the adhesive strength of the solid lubricant powder to the resin layer is secured. If the resin layer is composed of a thermoplastic resin, it is possible to adhere the solid lubricant powder in a plasticized state by heating. (Examples) Hereinafter, specific examples will be described. A detailed description of the manufacturing method will replace the detailed description of the structure of the friction material of the example.
