| description | The present invention relates to a friction material, a corresponding disc brake pad, and a braking system comprising said pad, in which the so-called "creep groan" phenomenon is suppressed or significantly mitigated. More in particular, the invention relates to a graphite-free friction material comprising: from 20 to 30% by volume of one or more abrasives; from 10 to 20% by volume of coke; up to 10% by volume of one or more metal sulfides; up to 20% by volume of one or more metals and/or metal alloys and/or intermetallic compounds in powder form; up to 40% by volume of a fibrous material comprising aramid fiber and steel fiber; from 10 to 20% by volume of phenolic resin as a binder; up to 10% by volume of one or more fillers selected from: calcium hydroxide, friction powder, PTFE, and fluorite.
La presente invención se refiere a un material de fricción, a una almohadilla de freno de disco correspondiente y a un sistema de frenado que comprende dicha almohadilla, en el que se suprime o mitiga de manera significativa el así llamado "gemido por arrastrado"; más en particular, la invención se refiere a un material sin fricción de grafito que comprende: de 20 a 30% en volumen de uno o más abrasivos; de 10 a 20% en volumen de coque; hasta 10% en volumen de uno o más sulfuros de metal; hasta 20% en volumen de uno o más metales y/o aleaciones de metales y/o compuestos intermetálicos en forma de polvo; hasta 40% en volumen de un material fibroso que comprende fibra de aramida y fibra de acero; de 10 a 20% en volumen de resina fenólica como un aglutinante; hasta 10% en volumen de uno o más rellenos seleccionados de: hidróxido de calcio, polvo de fricción, PTFE y fluorita. |
