This study aims to determine the mechanical properties of the use of brake pads
based on composite materials from bamboo fiber, and to evaluate the effect of replacement of
brake pad material made from asbestos with natural materials to avoid the impacts of
asbestosis substances, such as cancer. The method used several stages: weighing, mixing,
inserting materials in molding, compacting, and sintering. The stages were carried out in three
types of composites: Composite 1 (40% of bamboo fiber, 30% of MgO, and 30% of epoxy
resin), composite 2 (50% of bamboo fiber, 25% of MgO, and 25% of epoxy resin), and
composite 3 (60% of bamboo fiber, 20% of MgO, and 20% of epoxy resin). Tests for
mechanical properties were carried out using a standard analysis, such as wear rate using
ASTM D3702-94 standard, hardness test using ASTM D 785-03 type R, heat resistance using
2300 testing temperature, and composite brake lifetime analysis. The results showed that the
composition of bamboo brought great influences on the mechanical properties. The best
specimen had a wear rate of 0.9612.10-8 g/mm2
.s, hardness of 91.8 HRR, and heat resistance
at 280œC with a duration of 810 days. It is expected that the use of composite brake pads
made from bamboo fiber can replace brake pads made from asbestos, which is healthier and
safer to use.
