Method and device for the thermal treatment of friction linings

A method for thermally treating friction linings, comprising:

• emitting IR radiation with wavelength(s) in the range of 2260 nm to 3000 nm from one or more IR radiation sources comprising one or more ceramic IR radiators or ceramic IR heating fields that generate IR radiation with a maximum radiation power in the wavelength range from 2260 nm to 3000 nm;
• directing the IR radiation onto a friction lining body for a duration of 300 seconds to 2400 seconds to heat the friction lining body, wherein the friction lining body has a top surface and a surface opposite the top surface and defines a thickness between the top surface and the opposite surface, and wherein the heating directs IR radiation from the one or more IR radiation sources onto the top surface of the friction lining body;
• and
• detecting a surface temperature of the friction lining body for controlling the one or more IR radiation sources to maintain a desired temperature of the friction lining body top surface and opposite surface, wherein following the heating for the duration of 300 to 2400 seconds the desired temperature of the top surface of the friction lining body is in the range from 300° C. to 500° C. (572° F. to 932° F.), and the desired temperature of the opposite surface of the friction lining body is at least 300° C. (572° F.).
