The high-speed frictional behavior of the phenolic-resin based glass fiber composites has been studied. Although there have been many works on the brake materials for automobiles which usually contain fillers and modifiers in addition to the combination of the base resin and fibers (mostly asbestos), the role of each constituent for friction and wear of the composites is still unclear.
The purpose of this paper is to enable a clear interpretation of friction performance of the glass fiber composites at high speed friction. It has been shown that the frictional coefficient was much reduced by adding the glass fiber to the basic phenolic-resin. The frictional behavior became much stable in which the fluctuation of the frictional coefficient during sliding disappeared. It has also been shown that filling of the resin with high amount of glass fiber accelerates the wear rate at any sliding speed.
