NON-ASBESTOS FRICTION MATERIAL COMPOSITION, AND FRICTION MATERIAL AND FRICTION MEMBER USING SAME |
摘要 |
A non-asbestos frictional material composition containing a binder, an organic filler, an inorganic filler, and a fiber base material includes: copper in a content of 0.5 mass % or less as a copper element; a metal fiber other than a copper fiber and a copper alloy fiber in a content of 0.5 mass % or less; cashew dust in a content of 3.5-10.0, wollastonite, and mica. The non-asbestos frictional material composition can provide a frictional material with excellent friction coefficient, anti-crack properties, and abrasion resistance even with the reduced content of copper and a copper fiber possibly causing environmental pollution. The frictional material and the friction member are formed by using the above-mentioned non-asbestos frictional material composition. |
