 Abstract
In a study on the development of Cu-based sintered friction materials, the specimens pressed with various compacting pressures have been evaluated to find the optimum condition of compacting pressure. As compacting pressure increased up to , mechanical properties such as density, hardness, bending strength, wear and coefficient of friction, etc. improved remarkably, but up to 6 ton/cm, decreased slightly because of traps of gases and water vapors in specimen. Disk assembly composed of 12 pieces of Cu-based friction materials has been compared with one of asbestos-and nonasbestos-based friction materials. In dynamic and driving tests to find burst spin strength, corrosion area rate and friction properties, etc., Cu-based sintered friction materials showed better properties than the others, especially in severe conditions because oxides such as in the friction surface of friction materials were formed.
