Abstract

This research is dedicated to the study of the tensile properties of oil palm empty fruit bunch (OPEFB) fiber reinforced polypropylene (PP) and poly (lactic-acid) (PLA) composites. From the previous study, the investigation on tensile characteristic was done by using biodegradable polymers poly (lactic-acid) (PLA) on oil palm fiber in chopped random form. In this research the particle size of OPEFB was used in range size, 0.25mm to 0.063mm reinforced the PP and PLA. There are two major types of specimens which are differ in the composition. First type of specimens contain 10wt% of OPEFB loading with different particle size 0.063mm and 0.25mm labeled as OPEFB0.063-PP/PLA and OPEFB0.25-PP/PLA respectively. For this type of specimens were prepared by using method B. Second type of specimens contain 0.25mm OPEFB particle size with different fibre loading, 20wt% and 30wt% labelled as OPEFB20%-PP/PLA and OPEFB30%-PP/PLA respectively. For this type of specimens was prepared by using method A. In order to investigate the tensile characteristic of the composites tensile test was carried out for each specimen respectively. From the result, for 10wt% of fibre loading obtain 22.36MPa of tensile strength for OPEFB0.25-PP/PLA that is 52% higher than OPEFB0.063-PP/PLA that is 10.73MPa of tensile strength. For 0.25mm OPEFB particle size obtain 19.54MPa of tensile strength for OPEFB20%-PP/PLA that is 14.1% higher than OPEFB30%-PP/PLA obtain 16.82MPa of tensile strength. This result influenced by the porosity occur in the composites that was proved by doing liquid immersion test. Hardness test also was carried out to investigate the hardness properties.
