Abstract

[Abstract]: In the present work, effects of two types of natural fibres on mechanical properties of polyester composites were investigated at different volume fraction of fibre. Tensile, compression, and flexural properties of oil palm bunch and oil palm fruit fibres reinforced polyester composite were presented. In addition, tensile strength of the composites was calculated theoretically. Scanning electron microscope was used to observe the fracture mechanism of the specimens. Single fiber pull-out tests were carried out to determine the interfacial shear strength between polyester resin and oil palm fibres. As results, it was found that both type of oil palm fibres enhanced the mechanical performance of polyester composite. Improved tensile strength was evidence at higher volume fraction (≈41%).when polyester reinforced with oil palm fruit fibres, i.e. 2.5 folds improvement in the tensile strength. Further, experimental tensile strength of oil palm bunch/polyester composites was found to have less variation with the theoretical results compared to oil palm fruit/polyester composites. Flexural strength of polyester was worsened with oil palm fibres at all of fibre volume fraction.
