本发明是关于制动片、盘形制动片等汽车用摩擦材料的组分。过去用树脂粘合剂配合纤维状物质及其它填料而制成部件,用于汽车的制动上。但是这些部件由于反复使用,摩擦系数大为降低,摩擦系数试验不稳定。本发明鉴于上述问题,提供一种部件虽经反复使用而摩擦系数降低不大的摩擦材料的组分。本发明的摩擦材料主要成分是纤维状物 The present invention relates to a component of a friction material for automobiles such as a brake pad, a disc brake pad and the like. In the past with resin binder with fibrous material and other fillers made of parts for the car’s brake. However, due to repeated use of these components, the friction coefficient is greatly reduced, the friction coefficient test is not stable. In view of the above problems, the present invention provides a component of a friction material whose friction coefficient does not decrease so much, even though it is repeatedly used. The main component of the friction material of the present invention is a fibrous material
