Abstract
The invention relates to a method for producing a friction lining material as well as a friction lining material having a porous body, whose pores are filled with a filling material, said porous body being formed on the basis of petroleum coke.
Claims17
A friction lining material having a porous body, whose pores are filled with a filling material, wherein the filling material comprises a metal portion of at least 5% wt and wherein the porous body has a porosity of 5 to 50%, a bulk density of 1.5 to 5 g/cm3 and comprises more than 50 wt % of petroleum coke.
A method for producing a friction lining material, comprising the steps of compacting a mixture comprising petroleum coke and a binding agent containing carbon and subsequently pyrolizing the mixture at a temperature between 800° and 1500° C. in order to produce a porous body, then graphiting the porous body, and subsequently filling pores formed in the porous body with a molten filling material, wherein the molten filling material comprises a ceramic material.
A method for producing a friction lining material, comprising the steps of compacting a mixture comprising petroleum coke and a binding agent containing carbon and subsequently pyrolizing the mixture at a temperature between 800° and 1500° C. in order to produce a porous body, then graphiting the porous body, and subsequently filling pores formed in the porous body with a molten filling material, wherein the molten filling material comprises a semimetal material.
