Title:
FRICTION MATERIAL COMPOSITION AND PRODUCTION OF FRICTION MATERIAL THEREFROM
Document Type and Number:
Japanese Patent JPH10130627
Kind Code:
A
Abstract:

To obtain a friction material which has a stable coefficient of friction and does not cause noise or judder by incorporating a specified amt. of glassy carbon into a friction material compsn.

This friction material compsn. has a coefficient of friction (μ) of 0.35 or higher and a content of glassy carbon of 0.3-23wt.%. Glassy carbon is obtd. by curing a thermosetting resin and subjecting it to carbonization (1,000°C) and high-temp. treatment (2,000°C, graphitization). A furan resin, a phenol resin, an epoxy resin, etc., are used as the thermosetting resin, through there is no specific limitation. If necessary, a curative such as trichloroacetic acid, p-tolenesulfonic acid, or sulfuric acid is used. The compsn. may contain a binder (e.g. a phenol resin), a fibrous reinforcement (e.g. ceramic fibers, aramid fibers, or copper fibers), a lubricant (e.g. graphite), a filler (e.g. barium sulfate, rubber dust, or silica), a metal powder (e.g. brass), etc., in addition to glassy carbon.
