PENGARUH PERLAKUAN ALKALI, FRAKSI VOLUME SERAT, DAN PANJANG SERAT TERHADAP KEKUATAN TARIK KOMPOSIT SERAT SABUT KELAPA - POLYESTER
Abstract: Production of wood
in Indonesia is no longer able to meet their need, which is opening an
opportunity for study in material alternatives. Coconut fiber is very
potential material for
wood replacement composite,
since its availability is abundant
and its utilization
is still low.
Meanwhile, some factors
have been studied as single
affecting variable for
natural fiber composite.
The objective of this
study is to
evaluate the influence
factors of alkali
treatment, fiber length, fiber
volume fraction and
interaction between factors
on the tensile
strenght of coco-fiber polyester composite. 108 pieces
of composites have been prepared as speciments of
tensile test which
comply ASTM D
638 standard. The
testing result was processed
using completely randomized
full factorial
experiment. The experiment showed significant difference
for all three
factors. The highest value
of tensile strenght is 22.57 MPa
for 2 hours alkali treatment, 10 mm fiber length and
fiber volume fraction
of 35%. This
value has met
the standardminimum tensile
strength of hardboard according to ANSI A135.4 2004.
Keywords: composite, tensile
strength, coconutfiber, alkali
treatment, fiber length, volume
