Abstract
A method for forming a friction material. The method includes mixing a fibrous base material and filler particles to form a substrate. The method further includes saturating the substrate with a silane solution including a silane to form a uniformly impregnated silane matrix. The method also includes curing the uniformly impregnated silane matrix to form a cured uniformly impregnated silane matrix. The method also includes saturating the cured uniformly impregnated silane matrix with a phenolic resin solution to form a uniformly impregnated silane, phenolic resin matrix. The method also includes curing the uniformly impregnated silane, phenolic resin matrix to form the friction material.
