Title
(EN) Wet friction material production methods
Abstract
(EN)

A method of producing a friction material. The method includes mixing silica containing filler particles and a liquid binder to form a binder-filler liquid mixture. The method also includes saturating a fibrous base material with the binder-filler liquid mixture to form a saturated fibrous base material. The method further includes curing the saturated fibrous base material at a predetermined temperature for a predetermined time to cure the saturated fibrous base material to form the friction material.
