Abstract: A method of making a fibrous preform in carbon and/or fibres of a carbon precursor may include superposing at least two layers of carbon fibres and/or fibres of a carbon precursor according to a predefined superposition axis Z so as to form a multilayer body. The method may also include needle-punching via least one first needle-punching device the multilayer body in a needle-punching direction substantially parallel to the superposition axis Z to arrange at least part of the fibres parallel to the superposition axis Z, so as to obtain a needle-punched multilayer body. An optional step may include superposing with each other according to the superposition axis Z two or more of the needle-punched multilayer bodies, obtained separately by applying the above steps.

Abstract: A pad for disc brakes, a method for the manufacturing thereof, and a braking system with the pad are disclosed. The pad for disc brakes has a thickness y and a first surface cooperating with actuating means of a disc brake. The pad also has a second tribologically active friction surface that cooperates with the disc of the disc brake. The pad also has a first portion and a second portion, where the first portion of the pad extends for a thickness y1 from the first surface, and the second portion of the pad extends for a thickness y2 from the second tribologically active friction surface. The first surface and the first portion of the pad are made of carboceramic material, while the second surface and the second portion of the pad are made of carbonaceous material “C/C”.

Abstract: A shaped material (1, 1?), for example a disk for a disk brake, preferably a ventilated disk, includes a plurality of layers of material (6) in a spiral shape, overlapping along a development axis (X). Each layer of material (6) it is formed by a fabric (2) predominantly or exclusively made of carbon fibres (8), at least part of the layers being impregnated by an impregnating agent. A method is for the manufacture of a shaped material.

Abstract: Shaped material (1), in particular a disc for a disc brake includes layers (2, 4, 6) of carbon fibers stacked in a construction direction (X). Each layer (2, 4, 6) has segments (8, 10) placed side by side and joined together to form the layer, the segments of a layer (2, 4, 6) include radial segments (8) and transverse segments (10). In each layer (2, 4, 6) of carbon fibers, the number of transverse segments (10) is greater than the number of radial segments (8). A method manufactures a shaped material.
