Title:
化学的に活性化させた摩擦材
Document Type and Number:
Japanese Patent JP6556329
Kind Code:
B2
Abstract:
A friction material for a clutch or brake, including: a first surface facing in a first direction; a second surface facing a second direction, opposite the first direction; and a body portion sandwiched between the first and second surfaces. The body and the first and second surfaces include fiber material and filler material. The filler material for the first surface includes Si—OH (silanol) and Si—O—Na+ species. A torque converter including a torque converter clutch including: friction material including Si—OH (silanol) and Si—O—Na+ species; and a piston displaceable to engage the friction material with the piston and a cover to transmit torque from the cover to an output hub through the friction material and piston. A method of chemically activating friction material for a clutch or brake, including: exposing friction material, including filler material with Si—O—Si (siloxane), to NaOH (sodium hydroxide); and forming, from the Si—O—Si (siloxane), Si—OH (silanol).
