Karakterisasi Kekuatan Bending dan Hidrofobisitas Komposit Serat Kulit Waru (Hibiscus tiliaceus) Kontinyu Bermatrik Pati Ubi Kayu
Abstract: The development of
biopolymer becomes alternative solution of the waste problem which is mostly
produced by synthetic polymer. Biopolymer cassava extract which has big potency
to be developed as synthetic polymer alternative. Nevertheless, the basic
characteristic which is hydrofilyc and low tensile strength makes the polymer
film produced not acceptable to be used as
synthetic polymer alternative.
The method used in this
research was continous
fiber biocomposite by pressed hand lay up. The matrix was Wau wood fiber
which had layer variety 1,2,3,4 and the fiber directions 0o and 90
o.
The matrix biocomposite uses cassava extract with addition variation of
gliserol 5%,10%,15% of dry weight. The experiment testing used bending test standart
ASTM C 393
(1997) and moisture
test standart ASTM
D570-81. From this research, it was found that the highest
bending result on fiber variation 3 layers and 5 % matrix gliserol was 50,58
Mpa. The highest elongation on 15% gliserol+1 layer was 35%. The lowest moisture
test occurred on 1% laye and 5% matrix was 39.3%.
