PENGARUH VARIASI KOMPOSISI KOMPOSIT RESIN EPOXY/SERATGLASS DAN SERAT DAUN NANAS TERHADAP KETANGGUHAN
Abstract: Fiber of
pineapple leaf as one of
the natural fiber
which is very
abundant availability at
this time, but
is no longer used and disposed of
as waste. Though pineapple leaf fiber can be used as a natural alternative to
fiber composite materials. The
purpose of this
study was to
determine the effect
of variations in the
composition of the composite
epoxy / glass
fiber and pineapple
leaf fiber on
impact toughness, and
also can utilize
waste pineapple leaf fibers. Pineapple leaf fiber combined with glass
fibers in order to obtain optimum strength and toughness. Variation of weight
percent composition of the composite is 90:10, 80:20, 70:30, 60:40. The process
of manufacture of
the specimen is
done manually and
stirring pineapple leaf
fiber and glass
fiber with resin done
evenly and constantly.
Pouring resin into
the mold do
without the absence
of pressure. Of
the results impact test be
obtained impact energy and price of impact average for the composite with
composition 90:10 = 0.12 J for
impact energy and
for price impact
0.003 J/mm2, 80:20 =
0.0013 J for
impact energy and
price impact 0.0033 J/mm2, 70:30 = 0.32 J for impact energy and price
impact of 0.008 J/mm2, 60:40 = 0.31 J for impact energy and price impact
0.0077. Toughness is highest obtained on the 70:30 composition. From the test results it
can be concluded
that the natural
fiber – reinforced
composites and glass
fiber can improve
the toughness in the shock loads.
