Friction material for brake

摘要

A friction material for a brake obtained by a process which comprises preparing (I) a composition for a friction material from (A) a binder composition comprising 95-5 parts by weight of a cyanate ester resin and 5-95 parts by weight of a polycyclic aromatic pitch, (B) a fiber reinforcing substrate, and (C) a friction and wear regulator, thermoforming the composition (I) by hot pressing to cure the binder composition (A), and heat-treating the cured product at a temperature of 270 DEG -800 DEG C. to cyclize or semi-carbonize the binder composition (A) is disclosed which has markedly improved anti-fade properties.
