<p>From a general point of view, the present invention relates to a shaped composite material, particularly for braking applications, and to a method for its production. More particularly, the present invention relates to a composite ceramic material containing filaments constituted substantially by carbon, characterized in that it comprises a base layer and at least one surface layer on at least one of the faces of the base layer, and in that, in the surface layer, the filaments constituted substantially by carbon have a reactive contact surface large enough to enable a percentage of free carbon of less than (20)% by weight, preferably of between (5)% and (8)% by weight, calculated on the total weight of the at least one surface layer, to be obtained after a step of treatment with silicon.</p> |
