SLIDING MEMBER AND MANUFACTURE THEREOF

摘要

PURPOSE:To increase the coefficient of friction and to improve the strength and wear resistance by sintering a composite wherein specific uncharred carbonaceous fibers are imbedded in a self-sintering carbonaceous powder. CONSTITUTION:2-70 pts.wt. uncharred carbonaceous fibers (A) which are short fibers or long fibers having a fiber diameter of 3-100mum are sieved from a container having rectangular slits longer than the component A in the bottom while the container is swung in the longitudinal direction of the slits. 100 pts.wt. self-sintering carbonaceous powder (B) having a particle diameter of 30mum or less and a beta-resin content of 3-50% is sieved from a container having pores larger than the powder particle in the bottom. The components A and B are sieved alternatively from the containers to fill a mold with them, thereby obtaining a composite wherein the component A oriented in one direction is imbedded in the component B. Then the composite is sintered to obtain a sliding member whose sliding surface is perpendicular to the direction of orientation of the component A.
