Zeolite-coated steel fibers for friction materials applications

摘要

Zeolite-coated steel fiber used for non-asbestos organic type friction material was studied. High silica zeolite silicalite-1, due to its easy preparation procedures was chosen to be deposited onto the steel fibers. This work shows that the friction material incorporated with zeolite-coated steel fibers exhibit higher coefficient of friction values than the friction material with bare steel fibers. Zeolite-coated steel fibers added friction materials maintain a sufficiently high friction coefficient from 0.332 to 0.514 with the brake discs at high temperature from 150? to 300?. This kind of friction material with corrosion-resistant property has great potential to be used for vehicle brake pad applications.
