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...

Description
Summary: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. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
