    摘要： A friction material suitable for mating with a disk rotor or drum consisting mainly of an aluminum alloy reinforced by a hard material. The friction material suppresses the generation of a scoring on the disk rotor or drum. It also suppresses the change in the coefficient of friction before and after a heat history. The friction material comprises not only an organic-fiber base material, a binder resin, a friction-adjusting agent, a filler, and an inorganic powder, but also an inorganic fiber and a metal powder having a particle diameter of 1 to 180 &mgr;m.

    摘要： A method of forming a disk brake pad having a friction member composed of a bonding layer having a low porosity and a matrix layer having a high porosity and laminated on the bonding layer. The method does not require a pre-forming step. A material formed by pelletizing a mixture of components for the friction member and a non-pelletized material are fed one after the other into a cavity defined by a mold and a back plate. Also, since the pelletized material is compacted beforehand, the bonding layer formed from the pelletized material exhibits a sufficiently low porosity, so that the bonding layer can prevent moisture from infiltrating therethrough. Thus, the back plate is less likely to develop rust. Also, the bonding strength between the back plate and the bonding layer is improved. Further, since pelletized material forming the bonding layer penetrates into the matrix layer in a complicated manner, the bond strength between the bonding layer and the matrix is also improved.
