Zusammenfassung: | A friction material for a clutch comprising: a plurality of fibers; a filler material: and, a binder including at least 3% and at most 50% silane by weight based on total weight of the binder. The friction material is devoid of added water. In an example aspect, the silane is an organosilane having a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group. In an example aspect, the binder further includes phenolic resin, wherein the phenolic resin forms byproduct water upon curing to react with the hydrolyzable inorganic triethoxysilyl group to form a cross-linked binder. A method forming a hybrid matrix composite for a flexible clutch friction material is also disclosed. |
