PENGARUH FAKTOR JENIS KERTAS, JENIS PEREKAT DAN KERAPATAN KOMPOSIT TERHADAP KEKUATAN IMPAK PADA KOMPOSIT PANEL SERAP BISING BERBAHAN DASAR LIMBAH KERTAS
Abstract: Waste paper and
adhesive can be mixed as a noise absorber panel composite materials. This
composite materials can be applied
as a room
partition or core in
the sandwich composite.
The purpose of
this study is to
determine what factors those
influence the impact
strength of noise absorber
panel composite and the
combination of factor
levels that can produce
the best impact strength.
The preparation of
composite specimens was
conducted using a hydraulic press mold with two types of paper, office
paper (HVS) and newspaper, in a
variety of glueing
treatment, without glue,
PVAc glue and starch glue. The density was also varied of compaction
through the ratio of 2:1, 3:1, and 4:1.
Charpy impact test was conductedbased on ASTM D 5942-96 standardization. The
test used specimens with dimensions of 80 x 10 x 10 (mm3). The
results have shown
that the type
of adhesive, the
density and interaction between
the type of
adhesive and the
density of composite, influenced the
impact strength’s composite,
while the type
of paper factor haven’t. The
highest value of
impact strength have
determined in the composition mixture of HVS paper, starch
glue, and density of 4:1 are 9.51 x 10-3J/mm2
respectively. The sound absorption test was
the sound absorption in the medium
frequency (1000 Hz
- 2000 Hz),
the sound absorption coefficients (αp) required the ISO
11654:1997 (E) standardization that was at least 0.15.
For the frequency
of 1000 Hz,
αp = 0.15 and for
the frequency 2000 Hz, αp = 0.35.
