| Abstract | This work aims to study the influence of durian rind cellulose (DRC) microfiber as a reinforcing filler on the mechanical properties of polylactic acid (PLA) bio-composites. Cellulose from durian rind will be extracted using sodium hydroxide solution and bleached treatment with hydrogen peroxide. X-Ray fluorescence technique was used to examine the chemical composition of durian rind cellulose, and functional groups were analyzed using FT-IR technique. PLA was mixed with DRC microfibers particle size of 300 ?m by using a mixing apparatus, and then melt-blending by extruder in varying ratios of 100/0, 95/5, 93/7, 90/10, and 80/20wt%. The results revealed that the mechanical properties of PLA/DRC composites in the tensile modulus, flexural modulus, and shore-D hardness of the composites at DRC microfibers of 20 wt% was increased a maximum of 64%, 21%, and 16%, respectively, as compared to the neat PLA. On the other hand, the tensile strength, and flexural strength of the composites at DRC microfibers of 20 wt% was depressed by 9%, and 23%, respectively, as compared to the neat PLA. Polymer composites reinforced with DRC microfiber had increased water absorption when increasing DRC microfiber particles. PLA biocomposites as a new eco-friendly alternative material, and can be used to as compostable chopsticks. |
