A friction member is manufactured by: a cleaning step of cleaning a pressure plate of a friction member; a shooting step of shooting a shot material having a predetermined particle diameter under a dry condition to a surface of the pressure plate; an adhesive application step of applying a powder adhesive on the surface of the pressure plate; and a forming treatment step of bonding a pre-formed product of a friction material to the surface of the pressure plate.
摘要:
The present invention provides a thermosetting resin composite material excellent in mechanical strength and wear resistance at high temperature, which is achieved by converting graphite into thin-layered one and dispersing it in a thermosetting resin homogeneously. A thermosetting resin composite material, wherein an organically modified graphite having an organic compound molecule inserted between graphite layers is mixed with a thermosetting resin, the organically modified graphite being prepared by subjecting graphite to a chemical treatment to form a graphite interlayer compound having a low-molecular substance inserted between graphite layers and subsequently immersing the resultant product in a solution of an organically modifying agent, as well as a process for producing the same. Preferably, the organically modified graphite is mixed with a thermosetting resin to be converted into thin-layered one having a layer thickness of 0.1 to 100 nm, a layer length of 100 nm to 100 μm, and an aspect ratio of 100 to 1,000,000.
