US 2021/0277972 A1 · FRICTION MATERIAL

Abstract

A friction material includes a friction-generating layer and a base layer. The base layer includes base fibers and presents a bonding surface. The friction-generating layer includes friction-adjusting particles deposited on the base layer and presents a friction-generating surface facing opposite the bonding surface of the base layer. A curable resin is present in the friction-generating layer and the base layer. The friction material also includes a composition including a plurality of triglycerides. The composition is present in at least one of the friction-generating layer and the base layer. The plurality of triglycerides comprises polyunsaturated fatty acid in a content of from 60 to 90% by weight based on a total weight of the plurality of triglycerides included in the composition.
