PEMBUATAN DAN KARAKTERISASI PAPAN KOMPOSIT
BERBASIS SERAT DURIAN (DURIO ZIBETHINUS MURR) DENGAN
RESIN POLIESTER

ABSTRAK

Telah dilakukan pembuatan dan karakterisasi papan komposit berbasis serat kulit durian,
resin poliester dengan metode orientasi serat acak dengan panjang serat 2 cm, dengan
komposisi serat 0 gr, 0,1 gr, 0,2 gr, 0,3 gr, 0,4 gr, dan sudah dilakukan pengujian
mekanik dan fisis dan diperoleh nilai kuat tarik 39,165MPa, kuat lentur 46,439MPa,
kuat impak 13,65kJ/mm2, densitas 1,022/cm3, dan kadar air 2,00 %. Hasil penelitian
menunjukkan sifat mekanik dan sifat fisis yang memenuhi Standart JIS A 5905: 2003
yaitu kuat tarik > 0,4 MPa, kuat lentur >32MPa, densitas 0,3-1,3 gr/cm3 dan kadar air 5
%- 13 %. Komposit serat kulit durian dengan resin poliester dapat diaplikasikan menjadi
bumper mobil.
Kata kunci : poliester, komposit, serat kulit durian, sifat fisis, sifat mekanik.

PREPARATION AND CHARACTERIZATION OF COMPOSITES
BASED FIBER DURIAN (DURIO ZIBETHINUS MURR) WITH
POLYESTER RESIN

ABSTRACT

Preparation and characterization of composites based fiber durian with polyester resin
have been done by method of random orientation with a length of fiber 2 cm, the fiber
composition : 0 gr, 0,1 gr, 0,2 gr, 0,3 gr, 0,4 gr. The mechanical properties and physical
properties of composite were obtained as tensile strength 39,165MPa, flexural strength
46,439MPa, strong impact 13,65kJ/mm2 , density 1,022/cm3 and rate of water 2,00 %.
The results showed mechanical properties and physical properties are almost the same
as the Standard JIS A 5905 :2003 such as tensile strength >0,4 MPa,flexural strength
>32 MPa,density 1,07 – 1,3 gr/cm3and rate of water 5-13% It means the material on
this reseand can be applied to outomotive car such as bumper.
Keywords: polyester, composites,Durian leather fiber, physical properties, mechanical
properties.
