Title:
Non-asbestos friction material composition, friction material and friction member using this
Document Type and Number:
Japanese Patent JP6323539
Kind Code:
B2
Abstract:
Provided is a non-asbestos friction material composition containing a bonding material, an organic filler, an inorganic filler, and a fibrous substrate, said friction material composition being characterised by the content of copper in the friction material composition being at most 5 mass% as elemental copper, the content of metal fibres other than copper and copper alloys being at most 0.5 mass%, and containing lithium potassium titanium oxide and graphite. Even if the content of environmental pollutants such as copper and copper fibres is low, the non-asbestos friction material composition can provide a friction material exhibiting an excellent friction coefficient, crack resistance, and wear resistance. Further provided are a friction material and friction member using the non-asbestos friction material composition.
