As can be seen from the results in Table 2, compared to sintered friction material A that does not have insulating fibers, the insulating fibers are 10 to 70%
Sintered friction materials B to D having a heat insulating layer with a composite volumetric coefficient
The non-sliding surface temperature is low. In particular, for sintered friction materials with a heat insulating layer made of a 70 volume composite of heat insulating fibers, the temperature of the non-sliding surface is
