At the time of manufacturing the friction material (especially at the time of punching)
Yield is extremely poor. It is difficult to uniformly disperse additives (fillers, etc.) in the paper material during the papermaking process. Especially, when a fibrous material is added, the strength of the fibrous material is high because of its directivity. Variations in physical properties tend to occur. It is extremely difficult to make a sheet-shaped material with a uniform thickness and surface condition, especially in the sheet production by roll hot forming of an organic material (polymer material).
It takes time and effort. It takes time and effort to bond the friction material and the core material. For this reason, the conventional facing material requires many steps for its production, resulting in high production cost. Furthermore, in the case of a wet facing material, since it is used in oil, in order to improve the response response by removing the oil component from the facing surface during pressurization,
A groove called an oil groove is required. Conventionally, an oil groove is formed by cutting a paper material on a core plate to radially form an oil groove, or by forming a radial groove in the core plate itself.

It is necessary to increase the number of grooves in order to rapidly remove the oil from the facing surface, but even if a large number of radial grooves are provided, the facing surface center side (circumferential direction) On the side), the centrifugal force acting on the oil is smaller than that on the outer peripheral surface, so the removal of oil is delayed. As a result, the oil cannot be rapidly removed from the entire facing surface, and the characteristics tend to vary.
