PENGARUH VARIASI SUHU SIKLUS TERMAL TERHADAP KARAKTERISTIK MEKANIK KOMPOSIT HDPE–SAMPAH ORGANIK
Abstract: The aim
of this research is
to examine the
effect of thermal
cycling on the characteristic
of HDPE-organic waste composite including flexural strength, impact strength and shear
press strength. Composite is made from HDPE waste and organic waste (leaves and
twigs). The composite was
made by using
the pressured sintering
method. The pressured sintering
process was conducted
at 10 minutes
sintering time, temperature of
120 °C with
pressure of 8,7
kPa, and volume
fraction of HDPE of
0.3. Thermal cycling of
HDPE-organic waste composite
use temperature range 60, 70, 80,
90, 100, 110 °C. Thermal cycling compositesare tested in the form
of mechanical strength including the flexural strength and shear press referring to ASTM D1037, and impact referring to ASTM D5941. Besides,
the research observed the
fracture surface of bending test results
by using SEM (scanning electron microscopy) photos. Increased temperature
of cycle 60-110
°C will break
the bond between organic material
and HDPE that
affect the impairment
for bending is 56.93%,
for compression shear
71.75% and for
impact is 74.33%.
