Abstract:
In a dry friction material and a method for manufacturing the same, to maintain a content of glass fibers low on a whole dry friction material to apply a hole boring for caulking assembly with high strength and high stiffness at a part to be subjected to the hole boring.A part (glass-rich part 30) to be subjected to the hole boring is pressed at a higher pressure than a part not to be subjected to the hole boring in a press-shaping step by providing a rib 21 protruding toward a shaped body side on a part of press dies 20A, 20B corresponding to the part to be subjected to the hole boring. Thereby, only a compounded rubber 4 is pushed outward and only the glass-rich part 30 has an increase in a content of glass fibers 3. Thereby, strength that can withstand the hole boring is obtained. Accordingly, a dry friction material 1 with a bored hole 2 bored without generating a failure in the hole boring can be manufactured.
