Abstract

Nowadays, an oil palm industry generates a huge amount of agricultural waste in Malaysia such as oil palm trunk (OPT), oil palm frond (OPF) and oil palm fruit bunch (EFB). The remaining consist of biomass can be developed new material composite, where the (OPT) and (OPF) used as a reinforcement and Thermoplastic Polyurethane (TPU) used as a matrix. This research investigates the effect of oil palm trunk (OPT) and oil palm frond (OPF) fiber to physical and mechanical properties of Thermoplastic Polyurethanes (TPU). Prior to fabrication, the fiber was treated with 2% sodium hydroxide (NaOH) treatment and dried under the sun. Composite sample with four different volume fractions of oil palm fiber were fabricated, (0 wt %, 10 wt %, 20 wt % and 30 wt %). The samples were prepared by compressive molding method. The mechanical properties of composites were characterized by tensile test, flexural test and impact test. Interaction between fiber and matrix was observed by the scanning electron microscope (SEM) micrograph. Tensile test and flexural test of the composites were carried out using Instron 5960 dual column tester and the impact tests were conducted by Pendulum Impact Testing Machine. The density composition shows decreasing trend from 1.322 g/m³ at 0% to 1.186 g/m³ at 30%. Tensile strength significantly increases with an increase in fiber loading. The highest value of tensile stress 8.389 MPa at 30% fiber loading and the lowest tensile stress 7.073 MPa at 0% fiber loading. For flexural strength was found decreased 3.587 MPa at 20% fiber loading. Impact energy shows the increasing trend from 4.23 J/m at 0% to 6.0 J/m at 30% fiber loading. Tensile strength, flexural strength and impact energy significantly increased with an increasing of fiber loading.
