Abstract: A non-asbestos friction material contains a fibrous substance, a binder, and a friction modifier. The material contains no copper components, no carbonaceous raw materials, and no metal sulfides but contains an inorganic material having a laminar crystal structure and being different from the copper components, the carbonaceous raw materials, and the metal sulfides. Preferably, the inorganic material is at least one inorganic material selected from titanates, talc, kaolin, mica, vermiculite, and smectite.

Abstract: A friction material for a brake pad comprises a fibrous base material without a metal fiber, and comprises a binder and a friction modifier. The friction material comprises 0.3% to 2.0% by weight, relative to the entire friction material, of a non-crosslinkable polyolefin having a melting point higher than the melting temperature of the binder. The friction material can suppress increase in friction coefficient of a friction material during initial brake operation and reduce the occurrence of abnormal effects and squealing in low-temperature and high-humidity environments.
