Method for creating a block or layer of friction material without asbestos, including the following steps: a)- dissolve in water an alkaline silicate powder, preferably of sodium or potassium and, if necessary, sodium or potassium hydroxide, preferably commercial pellet or flake sodium hydroxide, to obtain a basic aqueous solution, at a pre-fixed pH, of the alkaline silicate and of a hydroxide in water; or dissolve in a basic sodium or potassium hydroxide solution under appropriate conditions a generic source of silica, such as quartz or colloidal silica, to obtain the said basic solution of an alkaline silicate and a hydroxide in water; b)- mix the aqueous solution of hydroxide and alkaline silicate with a material selected from the group consisting of metakaolin, kaolin, fly ash, mixtures of the same, preferably only commercial powder metakaolin, until a wet paste is obtained; c)- form and dry the wet paste until a dried geopolymer aggregate is obtained; d)- grind the dried geopolymer aggregate to a powder; e)- use the ground dried aggregate as an inorganic binder in a friction material compound, mixing it with inorganic and/or organic and/or metallic fibers, with at least one friction modifier or lubricant and with at least one filler or abrasive, so as to obtain a raw frictional material compound having as a binder almost exclusively or exclusively said ground dried geopolymeric aggregate, in which the geopolymer constitutes at least 90% in weight of the total quantity of binder present; f)- hot mold between 40°C and 300°C the raw compound under pressure greater than a water saturation pressure at the molding temperature to obtain a block of friction material wherein the binder is at least 90% in weight a geopolymer, so as the block of friction material is insensitive to heat degradation in use. a)- dissolve in water an alkaline silicate powder, preferably of sodium or potassium and, if necessary, sodium or potassium hydroxide, preferably commercial pellet or flake sodium hydroxide, to obtain a basic aqueous solution, at a pre-fixed pH, of the alkaline silicate and of a hydroxide in water; or dissolve in a basic sodium or potassium hydroxide solution under appropriate conditions a generic source of silica, such as quartz or colloidal silica, to obtain the said basic solution of an alkaline silicate and a hydroxide in water; b)- mix the aqueous solution of hydroxide and alkaline silicate with a material selected from the group consisting of metakaolin, kaolin, fly ash, mixtures of the same, preferably only commercial powder metakaolin, until a wet paste is obtained; c)- form and dry the wet paste until a dried geopolymer aggregate is obtained; d)- grind the dried geopolymer aggregate to a powder; e)- use the ground dried aggregate as an inorganic binder in a friction material compound, mixing it with inorganic and/or organic and/or metallic fibers, with at least one friction modifier or lubricant and with at least one filler or abrasive, so as to obtain a raw frictional material compound having as a binder almost exclusively or exclusively said ground dried geopolymeric aggregate, in which the geopolymer constitutes at least 90% in weight of the total quantity of binder present; f)- hot mold between 40°C and 300°C the raw compound under pressure greater than a water saturation pressure at the molding temperature to obtain a block of friction material wherein the binder is at least 90% in weight a geopolymer, so as the block of friction material is insensitive to heat degradation in use.
