れに有機繊維を混入させることが試みられている。(Prior art) Conventionally, as a friction material used for this type of clutch face and brake lining, asbestos fibers are used as the main material, and organic fibers are mixed in and combed to create twisted yarns or twisted yarns. The mainstream practice was to use friction materials that were formed by impregnating a woven material with a thermosetting resin solution made of phenol or the like to which rubber, carbon, etc. were added, and then drying and heating to harden the material. However, asbestos is manufactured as a cancer-causing substance.
Due to the recent situation where it is regulated and excluded at each site where it is handled and used, it is possible to use non-asbestos inorganic fibers such as glass fiber instead of asbestos in this friction material and mix organic fibers into this. is being attempted.

ていた。(Problems to be Solved by the Invention) These conventional friction materials are all made by adding rubber, carbon, etc. to a twisted yarn made by carding a mixture of inorganic fibers and organic fibers, or to a heavy body woven using this twisted yarn. It is made by impregnating it in a solution of thermosetting 11fW [II] made of phenol, etc., drying it, and then heating it.Since the main material is a mass consisting of twisted yarn or a heavy material woven with twisted yarn, it cannot be heated as a binder. The structure was such that the bonding with the curable resin was in a clearly distinct buried state, and a tight fusion state could not be expected. Therefore, in the composition of the friction material itself, the material is unbalanced, resulting in excessively high hardness in some areas and excessively low hardness, resulting in poor mechanical strength and frictional efficiency. .
