Abstract

This project focuses on the tensile and flexural properties of natural fibers composites and the effects of compatibilizer on mechanical properties. In this study, HDPE/kenaf composites with and without compatibilizer were produced. The composites were prepared with 20%, 30% and 40% (wt.%) of fiber content. Continuous kenaf long fibers were layered between the layers of HDPE and fabricated by the compression moulding method. A maleic anhydride compatibilizer is added together to enhance the interfacial bonding of matrix-fiber in the composites. Tensile and flexural tests were done on the samples and the improvements on interfacial bonding of matrix-fiber were proved under field emission scanning electron microscope (FESEM). The tested results were compared to the tensile and flexural properties of neat HDPE. It was observed that the effects of compatibilizer are significant on the tensile properties at 40% wt. of fiber content, with improvement of 214% and 347% on tensile strength and modulus, respectively. However, adverse effects of compatibilizer on tensile and flexural properties were observed in other fiber contents compared to that of specimens without compatibilizer.
