Development of brake lining based on mountain stone and shellfish waste

摘要

In general, brake pads made from asbestos, when used asbestos brake lining have a negative impact on health and the environment.In this research, a hybrid composite brake lining was developed with reinforcement of mountain stone powder, shellfish powder, and alumina with a certain composition.This paper describes the compression strength and water absorption ability of hybrid composite brake linings developed, as an alternative to brake pads that have good mechanical properties and are environmentally friendly.Hybrid composite brake lining material is made in seven weight fraction compositions through a sintering process.The test method is carried out by an experimental method based on ASTM E 9-89a for compression strength testing and based on ASTM D 570-98 for water absorption.The results showed that there was an influence of weight fraction on each composite variation on the compression strength of the brake lining.Reduction of percentage of mountain stone in each composition resulted in varying compression strength values, with the highest compressive strength value in specimen A of 0.1350 kN/mm~2 and the lowest in specimen G of 0.0883 kN/mm~2.Then the highest water absorption of the brake pad specimen made is 0.041558%, still lower than the asbestos brake lining pads.
