| dc.description.abstract | The brake pads have been done by using mixture of material : ramie fibers, areca
fiber, activated carbon as filler and epoxy resin as matrix through a dry
compression moulding technique with variation of composition ramie fibers :
areca fibers : activated carbon : epoxy resin 50% : 10% : 10% : 30%, 55% : 10% :
10% : 25%, 60% : 10% : 10% : 20%, 65% : 10% : 10% : 15% and 70% : 10% :
10% : 10%. The sample fabrication was done in two step. The first step, fibers
cutted by random of size ±0,5 cm. Then, fibers is mixed with epoxy resin until
homogenous about 5 minutes with dry mixing method. Second step, the fibers was
homogenized then it moulded with pressure 7 ton with holding time about 10
minutes. The moulded sampel were characterized such as : physical properties
(density, porosity and water absorption), mechanical properties (hardness strength
and wear rate) and thermal properties melting point by DTA (Differential Thermal
Analysis). The characterization result show that the optimum composition of
ramie fibers : areca fibers : activated carbon : epoxy resin was 50% : 10% : 10% :
30%, had the highest density 2,348 x 103 kg/m3, porosity 0,75%, water absorption
0,26%, hardness strength 100,252 x 103N/m, wear rate 9,259 x 10-3 kg/m2. sec and
melting point 410oC. The result of ramie fibers and areca fibers composite can
applied as replacement brake pads in market. | en_US |
