Abstract:
A friction material is discloses 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 said phenolic resin or phenol formaldehyde resin and of said thermoplastic is between 2 and 60% in volume of said 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.
