Abstract: A braking device has a portion having a braking surface adapted to come into contact with an opposite facing braking surface to apply a braking action, the braking surface being circumferentially free from obstacles to allow relative rotation between the braking surface and opposite facing braking surface when mutually in contact, and defining, in any point with respect to a revolution axis if the braking surface is fixed, or a rotation axis if the braking surface is rotative, an axial direction, a radial direction, a circumferential direction, and a tangential direction. A support connecting portion is radially outside the braking surface, either radially away from or outside the braking surface or either radially close to or inside the braking surface. A cooling portion, included circumferentially and laterally to the support connecting portion, has a plurality of axially through-openings adapted to increase a heat exchange surface and unadapted to create connecting surfaces.

Abstract: Method for making a ceramic matrix material for brake friction components, in particular disc brakes, including the following operational phases: a) prepare a mixture of at least one siliconic type ceramic precursor, particles of hard materials suitable as abrasives, particles of substances suitable as lubricants and particles of metal materials; b) hot-press the mixture to obtain a green body; c) submit the green body to a process of pyrolysis in order to achieve ceramisation of the preceramic binder, thus obtaining a ceramic matrix material. The mixture includes a catalyst suitable for favoring reticulation of the ceramic precursor during the hot-pressing phase and the pyrolysis process is carried out at temperatures below 800° C., more precisely between 400° C. and 600° C.

Abstract: Brake pad for braking systems, in particular for disc brakes, consisting of friction portion (10), tribologically active, and mechanical support portion (20) which is intended to cooperate with the actuating means of a braking system. At least friction portion (10) is made from a ceramic matrix material obtained with a method comprising the following operational steps: —preparing a mixture of at least one siliconic type ceramic precursor, of particles of hard materials suitable as abrasives, of particles of substances suitable as lubricants and particles of metal materials;—hot-pressing the mixture to obtain a preformed body;—submitting the preformed body to a process of pyrolysis in order to obtain ceramisation of the preceramic binder, thus obtaining the ceramic matrix material. The mixture comprises a catalyst suitable for favouring reticulation of said ceramic precursor during the hot-pressing step and the pyrolysis process is carried out a temperatures below 8000° C.
