摘要: Improved friction pads for use with disc brake. The pad has a central main portion and a peripheral portion which are formed of different matrices having different compositions. The matrix of the central main portion contains a hard substance or substances having a specified range of hardness whereas the matrix of the peripheral portion does not contain such hard substances or contains in only a limited smaller amount than the central main portion. This prevents the brake disc from wearing due to friction with the pad and thus avoids uneven abrasion of the brake disc.

摘要: A friction material containing 0.85 to 30% by weight of carbon fibers and 2 to 20% by weight of aramid fibers for use as brake pads, brake linings, clutch facings and other mechanical component parts which are subjected to severe frictional contact with other mechanical component parts. The aramid fibers preferably consist of para-aramid fibers and/or a combination of chopped aramid fibers and fibrillar aramide fibers. There is a certain preferred range for the ratio between the aramid fiber content and the carbon fiber content. This friction material offers advantages in a high-temperature stability of the coefficient of friction, a favorable wear property, freedom from sticking and uneven wears, and superior anti-fade properties.
