Development of Environmentally Friendly Brake Lining Material

Abstract

Materials commonly used as brake pads are asbestos and alloys, but this material is very dangerous to the environment and health. This research was developed to answer these problems, namely to look for alternative brake pads that have good mechanical and structural properties and are environmentally friendly. Brake lining pads material is made from hybrid composite reinforced basalt, shells, alumina and bound using phenolic resin polymer (PR-51510i). This brake pads material is produced through a sintering process with an emphasis of 2000 kg for 30 minutes at a fixed temperature of 160°C. This hybrid composite is made in as many as five variations, each of which is tested for wear resistance using a pin on disc test based on ASTM G 99-95a standards, while destilled water absorption test was based on ASTM D 570-98. The greatest wear rate is 0.000090 g/cm, which is still lower than wear rate of asbestos brake pad materials, and the highest destilled water absorption of the brake pads specimens obtained was 0.041558 still lower than the destilled water absorption of asbestos brake pads.
