Abstract
A friction-type member, which is suited, in particular, as a brake pad for a brake member of fiber-reinforced ceramic, and a method for manufacturing such a brake pad. A mixture is initially prepared from at least carbon particles and metal particles, if indicated, with the addition of polymer binding agents suited for pyrolysis; of hard material particles, such as silicon carbide or titanium carbide as abradants; and of solid lubricants, such as molybdenum sulphide or graphite, and subsequently cold-pressed into green compacts. Sintering is then carried out under vacuum or protective atmosphere, the organic binding agent concentrations initially being pyrolized, and the metal particles being at least partially bonded by reaction to carbon. The friction pads manufactured in this manner exhibit considerable mechanical strength, good frictional properties, as well as a high thermal loading capacity accompanied by a low rate of wear.
