Friction material and brake pad comprising such friction material

Abstract

A friction material is disclosed for a braking pad comprising a binder comprising a mixture of a phenolic resin or a phenol formaldehyde resin and of a thermoplastic. The total amount of phenolic resin or phenol formaldehyde resin and of thermoplastic is between 2 and 60% in volume of friction material. The ratio in volume between phenolic resin or phenol formaldehyde resin and the thermoplastic is from 20 to 80% in volume. Preferably the thermoplastic has a melting temperature between 120° and 350° C. and comprises a polyamide or a thermoplastic polymer with N-H bond, either in the backbone or in the pendant group. More preferably the thermoplastic material is chosen in the group constituted by PA4, PA6, PA1, PA11, PA12, PA410, PA610, PA66, PA612.
