Abstract

The main objectives of the present research are (i) to obtain a monoglyceride from oleic acid through a direct esterification process, (ii) utilization of the obtained monoglycerides to prepare polyurethane (PU) sheet, and (iii) the preparation of a series of biocomposites using prepared PU and different amounts of oil palm trunk (OPT) fiber dust. The tensile strength of OPT fiber dust incorporated PU biocomposites is found to be increased with the increase in the OPT fiber dust content up to 20% in the composites. The tensile strengths of PU and its biocomposites with 20% OPT fiber dust were 0.6 and 2.15 MPa, respectively. The thermal properties of PU and its biocomposites having varied amounts of OPT fiber dust of 0-40% have been investigated using dynamic mechanical analyzer (DMA) and thermogravimetric analyzer (TGA). TGA studies revealed that PU and its biocomposites have undergone two- and three-step degradation, respectively. From DMA studies, a shift in the tan ? value was noticed for the biocomposites containing 30 and 40% OPT fiber dust. The morphology of the tensile fractured composite specimens was analyzed using scanning electron microscope.
