Abstract:
1. A method for manufacturing a friction material including a phenolic resin as a binder, comprising: a molding process where a raw material for manufacturing the friction material including a thermosetting resin is pressed and heated in a mold, and a heat treatment process for curing the friction material, wherein said heat treatment process is designed to use a pair of upper and lower non-porous steel heat plates to directly contact to press and heat both upper and lower surfaces of one friction material, while leaving a side surface around the friction material open, a temperature of the heat plate is between 300 and 650° C., and a heat treatment time is between 2 and 70 minutes, thereby maintaining a predetermined wear resistance without causing cracks and blisters in a finished product.
