A friction material for a clutch pad comprising: a plurality of fibers; and, a filler material including at least 0.1% and at most 100% silica rich carrier particles by weight based on total weight of the filler; the silica rich carrier particles having: a median particle size of at least 0.1 m and at most 50 m; and, a median pore diameter of at least 0.1 and at most 10 m.

Friction assembly (1) comprising a support plate (2) and at least one brake pad (4), made by co-molding of at least one heat-resistant resin, the heat-resistant resin of the support plate (2) being partially loaded with non-metallic reinforcement fibers. The support plate (2) identifies one or more accessory-connection seat, made by co-molding. This invention further relates to a method for the manufacture of a friction assembly and a brake calliper.

A phenolic resin composition for friction materials includes a high-ortho novolac phenolic resin, a novolac resorcinol resin, and hexamethylenetetramine.

A wear resistant friction coating (WRFC) can be applied on a lightweight metallic substrate, by applying a cold gas dynamic spray bond coat containing more iron than any other single element directly onto a surface of the substrate, and thermal spraying the WRFC coating over the bond coat to a thickness of at least 500 m. Corrosion resistance, adhesion, thermal cycling resistance, and wear resistance have been demonstrated.

A brake pad of a disc brake, having a pad carrier plate and an intermediate layer which is fastened to the bottom surface thereof and carries an abrasive friction lining, is configured in such a way that the thickness of the unused friction lining is less than or equal to a predefined maximum wear dimension. The thickness of the friction lining plus part of the thickness of the intermediate layer correspond to the maximum wear dimension.

Friction assembly (1) comprising a support plate (2) and at least one brake pad (4), made by co-moulding of at least one heat-resistant resin, the heat-resistant resin of the support plate (2) being partially loaded with non-metallic reinforcement fibres.

A braking band having an annular band body arranged around a rotation axis and made of one of gray cast iron, steel, aluminum or alloys thereof, has at least one braking surface having an activated band body portion for increasing adhesive capacity of at least one protective surface coating placed on the surface of the activated band body portion and having at least one material with elevated resistance to abrasion. The activated band body portion is arranged on the surface of the annular band body to form an outermost layer of the braking band with the at least one protective surface coating and has a rough profile having at least one channel delimited by at least one pair of projections, extending along a path at least partially surrounding the rotation axis and having a channel bottom and a first channel side forming an acute angle with the channel bottom and an opposite second channel side forming an obtuse angle with the channel bottom.

A brake friction member includes a friction base material and a transfer film material. The friction base material is stacked on a back plate. The transfer film material is stacked on the friction base material and faces an opposing member. The transfer film material is made of a composition obtained by mixing an organic filler in an ultralow melting point resin component.
