Abstract
To provide the method for manufacturing the friction material for shortening the heat treatment process for completely curing the thermosetting resin in the friction material. The method includes the molding process for fixing the friction material onto a back plate, in which a raw material including a thermosetting resin is superposed onto the back plate, pressed and heated in the mold, and the heat treatment process for curing the friction material, using a pair of the heat plates provided at the back plate side and the friction material side to press the back plate surface and the friction material, and the heat plate temperature at the friction material side is between 300 and 650° C., at the back plate side is between 180 and 350° C., and the heat treatment time is between 2 and 70 minutes.
