Abstract: The present invention relates to a shaped material comprising an inner layer made of a carbon-based material, referred to as “Carbon-Carbon” or “C/C”, and respective outer layers made of a carbon-ceramic material comprising carbon and silicon carbide, preferably said material being shaped to form a disc brake disc.

Abstract: A method for manufacturing a brake pad preform for disc brakes is provided. The method involves preparing a thermosetting mixture by mixing a polymer resin in liquid form or particle powder form and ceramic particles in powder form, combining the thermosetting mixture with a carbonaceous material composed of carbon fibers to obtain a molding compound, molding the molding compound by compaction and heat treatment to obtain a crude preform, and subjecting the crude preform to a pyrolysis treatment to obtain the brake pad preform. A brake pad preform or a brake pad obtained by the manufacturing method is composed of a carbon-carbon composite composed of a matrix of carbonaceous material and carbon fibers in which the ceramic particles are uniformly dispersed in the matrix of carbonaceous material.

Abstract: A shaped material, for example, a disc for disc brakes, and a method for the manufacturing thereof. The shaped material has a plurality of layers of carbon fibers stacked along an overlap axis, each layer being formed by a plurality of radial segments and transverse segments. Each radial segment is adjacent and joined, on both sides, to a transverse segment and each transverse segment is adjacent and joined, on both sides, to a radial segment, forming in each layer an alternation of radial segments and transverse segments.

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 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 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.
