フェノール樹脂系複合材料の摩擦・摩耗に関する研究第4報 アラミド繊維充填フェノール樹脂の摩擦・摩耗挙動 Tribology of Phenolic-based Composites IV. Tribology of Phenolic-resin Based Aramid Fiber Composites
Phenolic-based composites for automotive frictional materials contain a variety of inorganic fillers and modifiers in addition to combination of the base resin and fibers (mostly asbestos). The frictional behavior under low speed conditions cannot provide sufficient foundation for the prediction of friction and wear behavior at high speed because the temperature rise courses chemical changes in some frictional constituents of the composite system.<br>In the previous papers the high speed friction behavior of carbon and glass fiber composites has been studied. The purpose of this paper is to enable a clear interpretation of high speed friction performance of Aramid fiber composites comparing with two other systems. The following results have obtained:<br>(1) Frictional coefficient was reduced by incoeporation of the aramid fibers under low speed and high speed conditions. However, frictional coefficient increased under medium speed conditions when the fiber content was high.<br>(2) Frictional flucturations during sliding was significantly reduced with increasing amount of fibers for all sliding condition.<br>(3) The rate of wear was reduced with increasing amount of fibers and increasing with sliding speed. The aramid-fiber system was more resistant to wear than carbon fiber and glass fiber systems.
