Evaluation of fade-recovery performance of hybrid friction composites based on ternary combination of ceramic-fibers, ceramic-whiskers, and aramid-fibers
Hybrid composite friction material based on ternary combination of potassium titanate whiskers, alumino-silicate ceramic fibers, and aramid fibers were fabricated and evaluated for their physical, mechanical, and tribo-performance. The frictional response, friction-fade, friction-recovery, and wear properties have been characterized on a Krauss friction tester following ECE R-90 regulation. Optimally, the composite with hybrid reinforcement incorporations in the form of ceramic-whiskers, ceramic-fiber, and aramid-fiber in the ratio of 13.75 : 13.75 : 2.5 has potentially been explored as a functionally feasible friction-material for braking applications. The interdependence of fade, recovery, disc temperature rise, and wear characteristics is established via thematic correlation diagram. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
