The disclosure describes a method of forming a carbon-carbon composite component including depositing an initial carbon material into a porous preform using chemical vapor deposition (CND) or chemical vapor infiltration (CVI) to form a rigidized porous preform, infusing the rigidized porous preform with an isotropic resin, pyrolyzing the infused isotropic resin to form an isotropic carbon within pores of the rigidized porous preform, and encapsulating the isotropic carbon, with a graphitizable carbon to form the carbon-carbon composite component.

A gasket is provided comprising a composite insulating component and a bonding resin. The insulating component is a ceramic abrasive and the bonding resin is a phenolic thermoset resin. The composite insulating component is selected from the group of alumina, zirconia, or silicon carbide. The gasket further comprises a reinforcing fiber selected from the group of glass, ceramic, aramid, or PAN fibers.

In some examples, a disc brake assembly and methods of forming and assembling said brake disc assembly. The brake disc assembly including a core structure and a plurality of wear pads. The core structure having a first major surface comprising at least one curved ridge or curved channel that extends in a radial direction along the first major surface between an inner and outer diameter of the core structure. Each wear pad defining a friction surface and a mounting surface such that the mounting surfaces of the plurality of wear pads are positioned adjacent to, and in contact with, the first major surface of the core structure, where at least one of the mounting surfaces of the plurality of wear pads includes a corresponding curved ridge or curved channel configured to interlink with the at least one curved ridge or curved channel of the core structure.

An interference fit connection for a shaft comprises a hub having a conical through opening and a reduction sleeve having a cylindrical through opening for arrangement on the shaft and a conical outer circumference, where the cone angle of the conical outer circumference corresponds to the cone angle of the corresponding conical through opening of the hub. The hub is a two-component part having a first component made of steel and a second component made of fiber-reinforced plastics material. The second component made of fiber-reinforced plastics material is designed as a ring which is arranged on the outer circumference of a sleeve portion of the first component, which sleeve portion surrounds the reduction sleeve, so as to surround this sleeve portion. The fiber-reinforced plastics material has a higher modulus of elasticity than the steel of the first component.

The invention relates to a method for producing a friction lining material as well as a friction lining material having a porous body, whose pores are filled with a filling material, said porous body being formed on the basis of petroleum coke.

In some examples, a disc brake assembly and methods of forming and assembling said brake disc assembly. The brake disc assembly including a core structure and a plurality of wear pads. The core structure having a first major surface comprising at least one curved ridge or curved channel that extends in a radial direction along the first major surface between an inner and outer diameter of the core structure. Each wear pad defining a friction surface and a mounting surface such that the mounting surfaces of the plurality of wear pads are positioned adjacent to, and in contact with, the first major surface of the core structure, where at least one of the mounting surfaces of the plurality of wear pads includes a corresponding curved ridge or curved channel configured to interlink with the at least one curved ridge or curved channel of the core structure.

A heat dissipation disc is for a clutch mechanism, and is incorporated into the clutch in a variable number, alternatingly intercalated between the friction discs of an oil-immersed multi-disc clutch. The heat dissipation disc is provided with inner or outer toothing for engaging either the crankshaft or the gearshift. The heat dissipation disc includes at least two solid outer steel discs and a central spacer disc, all of which are attached to one another concentrically like a sandwich. The central disc has a series of open grooves on its surface with an exit on one of the edges. The outer discs have several notches on one of the edges. The grooves and the notches determine an increased surface area on the edges of the dissipation disc.

A multi-plate clutch is comprised of: one or more core plates respectively coupled with a first rotary body rotatable about an axis; one or more reaction plates arranged alternately with the core plates and respectively coupled with a second rotary body rotatable about the axis, the reaction plates receiving the pressure force from the driver mechanism to brake the first rotary body relative to the second rotary body; one or more friction members respectively fixed to faces on the respective core plates, the faces to come into contact with the reaction plates, and including a bundle of warp yarns and a bundle of weft yarns mutually weaved perpendicular to each other, the yarns being formed of carbon fibers; and a plurality of bottomed grooves formed on faces on the respective reaction plates, the faces to come into contact with the core plates.

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.

A friction element having a friction layer or block made at least in part of a compounded friction material having a homogenous fibrous microstructure, in which the fibrous aspect of the homogenous microstructure appears to be lost up to a magnification of 100. The friction material is obtained with a mixing step including a first step of hot blending of at least part of the organic binder with at least part of the other components of the friction material by a rolling mill blender that is open to atmospheric pressure at a temperature lower than the polymerization temperature of the organic binder but greater than or equal to its softening temperature, in order to obtain a semifinished solid product. A second step of grinding the semifinished solid product reduces the product to a powder.
