Manufacturing Brake Pads by Using Hot Powder Preform
To develop a high density brake pad for low duty application a P/M route based on Hot Powder Preform Forging was developed which is not possible by sintering route. The mechanical properties of these materials were characterized using ASTM standards. The limitations of the conventional technique i.e. Compacting and Sintering for the manufacture of brake pads were tried to remove by
