摘要： The present invention provides a binder resin for a friction material, which enables high-temperature short-time thermoforming and can omit a post-curing step and suppress the generation of a pyrolysis component at molding; a friction material using the binder resin; and a binder resin composition for a friction material, which is enhanced in the heat resistance and can suppress a rapid increase of the wear amount, and in addition to these properties, which has good dynamic property and enables high-temperature short-time thermoforming. The present invention relates to a binder resin for a friction material which comprises (A) one kind or two or more kinds of polybenzoxazine resins selected from a condensation reaction product of an aminophenol compound with formaldehydes and a condensation reaction product of a bifunctional phenol compound and a bifunctional amine compound with formaldehydes; a binder resin composition for a friction material which comprises: the component (A); and further (B) one kind or two or more kinds of particles selected from an inorganic particle and an inorganic-organic composite particle, and a friction material obtained by the binder resin or binder resin composition.

摘要： A friction modifier is provided with a titania particle-layered clay mineral complex in which titania particles are contained in a layered clay mineral. An average particle diameter of the titania particles is 3 to 100 nm. A ratio of the titania particles to the titania particle-layered clay mineral complex is 0.1 to 0.8 on the mass basis.
