摘要: The invention provides a friction member having high heat resistance and wearing resistance useful as a brake shoe or brake block in traffic vehicles and industrial machines. The friction member is prepared by consolidating a fibrous base material, e.g. asbestos, with a resinous binder which is a phenolic resin modified with an organopolysiloxane which characteristically comprises, in a molecule, at least one tetrafunctional siloxane unit of the formula SiO.sub.2 and/or at least one trifunctional siloxane unit of the formula R.sup.1 SiO.sub.1.5, in which R.sup.1 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 8 carbon atoms.
