摘要： [Object]
To provide the friction material for the disc brake pad such as an automobile, which is manufactured by forming the NAO friction material composition, enabling to restrain the brake vibration during braking in a high temperature.
[Means to Resolve]
In the friction material, which is manufactured by forming the NAO friction material composition that does not contain the copper component but contains the binder, the fiber base, the organic friction modifier, the inorganic friction modifier, and the lubricant, the friction material composition contains 5 - 9 weight % of the binder relative to the entire amount of the friction material composition, 1- 4 weight % of the silicone rubber modified phenol resin as a part of the binder relative to the entire amount of the friction material composition, 1 - 4 weight % of a cashew dust as the organic friction modifier relative to the entire amount of the friction material composition, 0.5 - 3 weight % of a fused silica with the average particle diameter of 15 - 40µm as the inorganic friction modifier relative to the entire amount of the friction material composition, and 0.1 - 2 weight % of the electromelting zirconium silicate beads with the average particle diameter of 10 - 30µm as the inorganic friction modifier relative to the entire amount of the friction material composition.
