FRICTION MATERIAL COMPOSITION AND FRICTION MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a friction material composition suitable for a friction material capable of diminishing both low-frequency noise production and noise pressure at high absolute humidities and after car parking overnight, and to provide such a friction material. SOLUTION: This friction material composition contains fluororesin-coated organic fibers. The other objective friction material is obtained by hot-press molding of the above composition.
