(8pp) EPAB- EP-149726 B A friction material comprising: 3-16% by weight polystibazole resin; and balance filler material. USAB- US4476256 A Material comprises 3-16 wt% polystilbazole resin, the balance being filler material. - The polystilbazole resin is polystyryl pyridine (I), which is pref. addn. curing , and is used at 6.5-10 wt%. The fillers comprise 10-50 wt% metal fibres, e.g. 34-42% steel fibres; 22-68 wt% metal powder, e.g. 22-26% iron powder; 2-28 wt% carbon, e.g. graphite or carbon black; 1-11 wt% ceramic powder, e.g. alumina zirconium silicate, talc and/or magnesia and 12-14 wt% barytes.
