A friction pad body having a backing part and a friction part, which integrally consist of the same ceramic material, without a seam and joint. The ceramic material has a purity of at least 80% in relation to the total weight of the friction pad body. The friction pad body is preferably produced in the form of a sintered body by isostatic pressing so that a single-stage production process can be achieved.

Provided is a friction member (such as a disc brake pad) having light weight by reducing weight of a back plate and having improved durability after repeated braking. Specific examples of the friction member include a friction member having a friction material disposed on one surface of the back plate comprising a material having a lower specific gravity than that of steel, wherein heat conductivity in a thickness direction of the friction material is 0.40 W/m.Math.K or less.

The present invention is concerned with a frictional material composition not containing copper as an element or having the content of copper of 0.5 mass % or less, the composition containing a cashew dust; (A) potassium titanate; (B) one or more selected from the group consisting of lithium potassium titanate and magnesium potassium titanate; and (C) one or more selected from the group consisting of zirconium silicate, zirconium oxide, and magnesium oxide, wherein the content of the cashew dust is 1 to 10 mass %, and the content of the component (C) is 11 to 30 mass %.

A method of manufacturing a brake pad including a friction pad and a mounting structure includes providing a cure mold; filling the cure mold with granulated thermoset plastic to form the mounting structure and particulate friction material to form the friction pad; and press curing in a single step the filled cure mold to form the brake pad.

Provided are a brake pad for a disc brake including a resin back plate and a friction material joined to one surface of the resin back plate, in which the resin back plate is formed of a cured product of a first thermosetting resin composition, and a metal reinforcing material is provided on a surface of the resin back plate opposite to the surface joined to the friction material or inside the resin back plate, and a method of manufacturing the brake pad.

A brake shoe having brake linings for a brake apparatus includes a carrier element, and a first brake lining segment configured to be mounted on the carrier element, and a second brake lining segment configured to be mounted on the carrier element, the first brake lining segment and the second brake lining segment being spaced apart from one another in a mounted state, and the first brake lining segment and the second brake lining segment differing from one another with regard to material composition, force loading and/or shape to configure a friction profile.

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 y.sub.1 from the first surface, and the second portion of the pad extends for a thickness y.sub.2 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.

A friction assembly has a support plate, at least one brake pad and at least one reinforcing foil of the plate. The brake pad and the support plate are co-moulded from at least one heat-resistant resin. The reinforcing foil is fixed to the support plate via anchoring projections, joined to and which extend away from the foil, embedded in the resin to prevent or limit deformations of the support plate in the use of the assembly.

The present invention is concerned with a frictional material composition not containing copper as an element or having the content of copper of 0.5 mass % or less, the composition containing

(A) potassium titanate; and

(B) one or more selected from the group consisting of lithium potassium titanate and magnesium potassium titanate,

in a total content of the component (A) and the component (B) of 10 to 35 mass %, wherein

on heating a molded product of the frictional material composition to 500 C. at a temperature rise rate of 10 C./min under an air atmosphere, the mass reduction rate is 5 to 20%.
