PENGARUH WAKTU PEMAPARAN CUACA (WEATHERING) TERHADAP KARAKTERISTIK MEKANIK KOMPOSIT HDPE – SAMPAH ORGANIK
Abstract: This research
aimed to determine
the effect of
weathering exposure time
on mechanical characteristics
which include bending
strength, compression shear
strength, and the impact strength of HDPE-organic waste composites.The materials
use in this
research were HDPE
and organic waste.
The composite was made
by using the
pressured sintering method
with pressure 8,7 kPa,
temperature 120º C,
sintering time 10
minutes, volume fraction
of HDPE is 0,3
and organic waste
is 0,7. Speciment
was directly exposed
to weather with variations in 0 month (no treatment), 1 month, 2 months,
and 3 months (ASTM D1435). Testing the
bending strength and compression shear strength refers to ASTM
D1037. The surface of bending fracture was observed by using Scanning Electron
Micrograph (SEM).Weathering
exposure for 3
months has not
effect on bending
strength and compression shear
strength, this is
causes the bond
between HDPE and organic waste not yet demage during 3
months exposure
