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.

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.
摘要翻译：改进的用于盘式制动器的摩擦垫。垫具有由具有不同组成的不同基体形成的中心主要部分和周边部分。中心主要部分的基质含有硬物质或具有特定硬度范围的物质，而周边部分的基质不含有这些硬质物质，或仅含有比中央主要部分少的量。这样可以防止制动盘由于与垫的摩擦而磨损，从而避免制动盘的不均匀磨损。
