SIFAT MEKANIK KOMPOSIT BERBASIS POLI ASAM LAKTAT (PLA) DAN SERAT SELULOSA TANDAN KOSONG KELAPA SAWIT
ABSTRACT: Poly lactic acid
(PLA) is thermoplastic plastic that have potential to replace conventional plastic
because it have advantages such as biodegradable and sustainable. But PLA haveweakness
like fragile. The aim of this study is evaluate mechanical properties of composites
PLA with additon oil palm empty fruit bunches (EFB) cellulose fibers. The
composition of EFB cellulose fibers were 0, 5, 10, 15 and 20 Per Hundred Resin
(PHR). Testing sample test sample using Shimadzu Universal Testing Machine with
load speed 1 mm / minute and 70 mm gauge length, based on ASTM D-638-02a
standard. The sample length is 110 mm, width 6 mm and thick 0,7 mm. All
displayed average of 3 repetitions. The results showed that tensile strengthand
elongation composites neat PLA highest than composite PLA with EFB cellulose
fibersshowing value respectively 40,20 MPa and 4,25%. The highest value for
young modulus incomposite PLA with cellulose fiber was noted at 15 PHR EFB
cellulose fibers with value of 3,96 GPa.
