In this research,
biocomposite was prepared by using coconut fiber as filler and polylactic acid (PLA) as matrix.
Coconut fiber undergo three different treatments which are sodium hydroxide,
bleaching and maleic anhydride. Biocomposite was produced by varied composition
of coconut fiber into 2%, 4% and 6% to be added into PLA. Characterization of
coconut fiber was carried out by using infrared spectroscopy analysis (FTIR)
analysis in order to study the changes in functional groups and degree of
crystallinity of coconut fiber after treatment. Characterization of the
biocomposite produced was carried out by using mechanical test to study the
mechanical properties of biocomposites. Based on the results from FTIR
analysis, certain functional group in original coconut fibre structure
disappeared after chemical treatment. XRD analysis also showed that bleached
coconut fibre has the highest crystallinity. Overall, the result from tensile
test showed that maximum load and the modulus Young of biocomposite increase
with increase composition of coconut fiber until an optimum point which is at
2% coconut fiber. While elongation at break decreased with increasing
composition of coconut fiber.
