Abstract

Oil palm empty fruit bunch (EFB) reinforced composite is an emerging area in polymer technology. EFB is a low cost filler with low density, high specific properties as well as being nonabrasive. The objective of the work reported is to study the effect of particle size on mechanical properties (flexural and tensile properties) of EFB-polyethylene composites. Three different particle sizes of EFB have been prepared using 0-150 Jlm, 150-300 Jlm, and 300-425 Jlm. Five formulations of varying content of EFB have been prepared for each filler sizes (0%, 10%, 20%, 30% and 40%). Flexural and tensile test has been carried out to determine the mechanical properties of the composites. For all three filler sizes, tensile strength decrease gradually with increase in EFB fiber content. However, both tensile and flexural modulus showed no significant improvement because the modulus had to be calculated manually and subjected to human error but there were part of tbe result showed considerable improvement. Samples have also been subjected to microstructure observation using scanning electron microscopy (SEM). From the morphology, it showed that the fiber and matrix interface is very low thus the stress concentration is high. Besides, irregular orientation of the fiber distribution have resulted small improvement of mechanical properties. Particle size is important to achieve good combination of mechanical properties.
