Abstract: This study aims to
investigate the coefficient of friction and tensile strength of composite materials
of teak sawdust
charcoal with Epoxy
matrix. Sawdust charcoal made
at a temperature
of 200 and
300 Celsius degrees
for two hours. Two
kinds of charcoal
are used as
filler composites by
varying the composition of
charcoal with constant
total filler content
of 40 percent
(v / v).Then the
tensile test and
the measuring of
friction coefficient of the
composite is conducted.
The variation of
composition that gives
tensile strength and the best friction coefficient, then made a
composite material by varying the content of filler / particles from 27, 36, 45 and 54 percent (v/v). The composites
were developed with
a hydraulic press
mold method. The results
showed that at
the variation of
composition of charcoal, the
highest tensile strength occurred in the composition of a mixture
of 100% charcoal 200 Celsius degree
(0% charcoal 300 Celsius degree)is about 21 MPa. The largest friction
coefficient also occurred
in this composition
is 0.55. At the
variation of filler content, the highest tensile strength occurred at 36
percent particle content is about 19.5 MPa. The value of friction coefficient
increases with increasing filler content in composite.
