A friction material for brake pads comprising a binding composition comprising Portland cement type I 52.5R with a Blaine fineness of 6500 cm2/g, water and a multi-component mixture comprising components including a lubricant, an abrasive, a component containing carbon, and a modifier, said components selected from metallic oxides, steel fibres, aramid fibres, chromite, metallic sulphides, graphite, coke, metallic powders, barite and rubber, the binding composition being present in a percentage ranging from 5 to 30% by weight with respect to the total weight of a mixture constituting the friction material.
A friction material for brake pads comprising a binding composition comprising Portland cement type I 52.5R with a Blaine fineness of 6500 cm2/g in a percentage ranging from 5 to 30% by weight, water in a percentage ranging from 5 to 20% by weight, and a multi-component mixture comprising a lubricant in a percentage ranging from 5 to 15% by weight, an abrasive in a percentage ranging from 8 to 25% by weight, a component containing carbon in a percentage ranging from 8 to 25% by weight, and a modifier in a percentage ranging from 15 to 30% by weight, all the percentages being computed with respect to the total weight of the composition constituting the friction material.
A method of using a binding composition for the achievement of a friction material for brake pads, the binding composition comprising Portland cement type I 52.5R with a Blaine fineness of 6500 cm2/g, comprising the step of mixing the binding composition with water and a multi-component mixture comprising components including a lubricant, an abrasive, a component containing carbon, and a modifier, said components selected from metallic oxides, steel fibres, aramid fibres, chromite, metallic sulphides, graphite, coke, metallic powders, barite and rubber, where the binding composition is present in a percentage ranging from 5 to 30% by weight with respect to the total weight of a mixture constituting the friction material.
